A rectangle and a square have the same perimeter (Fig. 6.10). A. The area of the rectangle is _________. B. The area of the square is _________. Fig. 6.10

Question

Philoid · Accepted Answer

Given:

Length of rectangle, l = 5 cm.

Breadth of rectangle, b = 3 cm.

Perimeter of rectangle = 2 × (l + b)

= 2 × (6 + 2)

= 2 × 8

= 16 cm

Perimeter of square = 4 × side

16 = 4 × side

Side = 16 / 4

∴ Side of Square = 4 cm.

Area of rectangle = l × b

= 2 × 6

= 12 cm²

Area of square = side²

= 4²

= 16 cm²

A. The area of the rectangle is 12 cm².

B. The area of the square is 16 cm².
