Question

The area of a square is 64cm2. A rectangle has the same perimeter as the square. If the length of the rectangle is 9 cm, find its breadth.​

Answer 1

Answer:

7 cm

Step-by-step explanation:

Let the side of a square be x

x x x = 64

x = 8cm

Perimeter of square = Side x 4 cm

8 x 4 cm

32 cm

Perimeter of square = Perimeter of rectangle

32 cm = 2 (1+b)

32 cm = 2 ( 9 + b)

32/2 = 9 + b

16 cm = 9 + b

b = 16-9

b = 7cm
