Kya koi ye question solve kar sakta he please help...The area of the rectangle is 75% of the area the square. If breadth of the rectangle is 75/2% of the side of the square and difference between length and breadth of the rectangle is 91 cm, then the perimeter of the square will be what percent of the perimeter of the rectangle?
To solve the problem, let's start by defining the variables and equations based on the information given: 1. Let s be the side length of the square. The area of the square is: 2. Let I and b be the length and breadth of the rectangle, respectively. The area of the rectangle is: 1xb 3. According to the problem, the area of the rectangle is 75% of the area of the square. Therefore: Ixb-0.75 x s² 4. The breadth of the rectangle is given as % of the side of the square. 2 Converting to a decimal: 75 %-37.5%-0.375 Hence: b-0.375x8 5. The difference between the length and breadth of the rectangle is 91 cm. Therefore: 1-b-91 Substitute b-0.375 x 1-0.375xs-91 Solving for 1: 1-91-0.375 x s 6. Substitute 1 and b into the area equation: 1-91+0.375 x s 6. Substitute / and b into the area equation: 1xb-(91+0.375 x 3) x 0.375xs-0.75 x 82 Simplify: (91 x 0.375 x 3) + (0.3752x8²) -0.75 x s² 2 34.125x8 +0.140625 x s² 2 0.75 x s Subtract 0.140625 x s² from both sides: 34.125 x $0.609375 x s² Rearranging: 34.125 0.609375 Calculate: s-56 cm 7. Now find I and b b-0.375xs-0.375 x 56-21 cm 1-91+0.37556-9121112 cm 8. Perimeters of the square and rectangle: Perimeter of the square: 4x-4x56224 cm Perimeter of the rectangle: 2x (1+b)-2x (112+21)-2x133-266 cm 9. Calculate the percentage: Perimeter of the square Percentage Perimeter of the rectangle x 100% Percentage 224 266 10084.96% Thus, the perimeter of the square is approximately 84.96% of the perimeter of the rectangle.
Great 🙂finally got actual concept. I saw many vidieos but this was 🔥🔥
Thank you so much 🙏
Can't wait
Keep it up
Good Explanation
Thank you 😊
DIY ans: 0.52
Solution:
Ratio of 210/403 can be approximated to 1/2
403 is 3 more than 400
403-3=400
3/2 = 1.5 can be approximated to 2
210-2=208
Therefore,the ratio now becomes,
208/400
208/4=52
52/100=0.52
And that's our answer.Hope it helps.
Thanks Ma'am for this trick
And ma'am also Pls give a trick for multiplication of big numbers.
Have a nice day. 😊😊
My pleasure will do trick on big numbers multiplication soon
@@FastandEasyMaths Thanku ma'am
Kya koi ye question solve kar sakta he please help...The area of the rectangle is 75% of the area the square. If breadth of the rectangle is 75/2% of the side of the square and difference between length and breadth of the rectangle is 91 cm, then the perimeter of the square will be what percent of the perimeter of the rectangle?
To solve the problem, let's start by defining the variables and equations based on the information given:
1. Let s be the side length of the square.
The area of the square is:
2. Let I and b be the length and breadth of the rectangle, respectively. The area of the rectangle is:
1xb
3. According to the problem, the area of the rectangle is 75% of the area of the square. Therefore:
Ixb-0.75 x s²
4. The breadth of the rectangle is given as % of the side of the square. 2 Converting to a decimal:
75 %-37.5%-0.375
Hence:
b-0.375x8
5. The difference between the length and breadth of the rectangle is 91 cm.
Therefore:
1-b-91
Substitute b-0.375 x
1-0.375xs-91
Solving for 1:
1-91-0.375 x s
6. Substitute 1 and b into the area equation:
1-91+0.375 x s
6. Substitute / and b into the area equation:
1xb-(91+0.375 x 3) x 0.375xs-0.75 x 82
Simplify:
(91 x 0.375 x 3) + (0.3752x8²) -0.75 x s² 2
34.125x8 +0.140625 x s² 2 0.75 x s
Subtract 0.140625 x s² from both sides:
34.125 x $0.609375 x s²
Rearranging:
34.125 0.609375
Calculate:
s-56 cm
7. Now find I and b
b-0.375xs-0.375 x 56-21 cm
1-91+0.37556-9121112 cm
8. Perimeters of the square and rectangle:
Perimeter of the square:
4x-4x56224 cm
Perimeter of the rectangle:
2x (1+b)-2x (112+21)-2x133-266 cm
9. Calculate the percentage:
Perimeter of the square
Percentage Perimeter of the rectangle x 100%
Percentage 224 266 10084.96%
Thus, the perimeter of the square is approximately 84.96% of the perimeter of the rectangle.
