Homework answer: Area of the rectangle= l x b Area= 8cm x 5cm = 40cm square 1.5cm along its sides margin area = 2 x ( ( l +b ) x 1.5 ) =2 x (( 8cm + 5cm ) x 1.5 ) = 2 x (13cm x 1.5 ) = 2 x 19.5cm = 39cm square margin area that gets overlapped or doubled is 1 square on each corner of the rectangle total no. of squares = 4 side of square = 1.5cm area of square = side x side = 1.5cm x 1.5cm = 2.25cm square area of 4 squares = area of one square x 4 = 2.25cm x 4 = 9cm square Area of the margin = margin area - area of the 4 squares = 39cm square - 9cm square = 30cm square Therefore, THE TOTAL AREA OF THE MARGIN IS 30cm square.

Homework answer:
Area of the rectangle= l x b
Area= 8cm x 5cm
= 40cm square
1.5cm along its sides
margin area = 2 x ( ( l +b ) x 1.5 ) =2 x (( 8cm + 5cm ) x 1.5 )
= 2 x (13cm x 1.5 )
= 2 x 19.5cm = 39cm square
margin area that gets overlapped or doubled is 1 square on each corner of the rectangle
total no. of squares = 4
side of square = 1.5cm
area of square = side x side = 1.5cm x 1.5cm
= 2.25cm square
area of 4 squares = area of one square x 4
= 2.25cm x 4 = 9cm square
Area of the margin = margin area - area of the 4 squares
= 39cm square - 9cm square = 30cm square
Therefore, THE TOTAL AREA OF THE MARGIN IS 30cm square.
Your explanation is nice mam...
