f) The perimeter of square B is ____ times the perimeter of square A.​

Answer 1

Answer:

The length of piece A is 6 cm. So, 6 squares of side 1 cm can be arranged along its length.

The width of piece A is 5 cm. So, 5 squares can be arranged along its width.



• Altogether 30 squares can be arranged on it. • So, the area of piece A =  6 cm

× 5 cm = 30 square cm

• Now, the area of piece B =  11 cm

×3 cm = 33 square cm

• So, the area of piece B is bigger than the area of piece A. Difference in area of piece A and piece B = 33 square cm − 30 square cm = 3 square cm

So, piece B is 3 square cm bigger than piece A.
