Answer 2

Answer:

Perimeter of rectangle = 2 ( 12 + 8)

= 2 x 20

= 40 cm

Perimeter of square = 4 x Side

40 = 4 x Side

40/4 = Side

10 cm = Side

Area of rectangle = l x b

= 12 x 8

= 96 cm²

Area of square = Side x Side

= 10 x 10

= 100 cm²

Area of square > Area of rectangle

100 cm² - 96cm²

4cm²
