Question

Which has greater perimeter: a square of side 12 m or a rectangle of sides 15 m
and 8 m?​

Answer 1

Answer:

perimeter of square=4a=4×12=48m

perimeter of rectangle=2(l+b)=2(15+8)=2×23=64m

rectangle has greatest perimeter

Answer 2

Answer:

Perimeter of square = 4 x side

= 4 x 12 m

= 48 m

Perimeter of rectangle = 2 x (l+b)

= 2 x (15 +8)

= 2 x 23

46 m

SINCE 48 IS GREATER THAN 46 SO SQUARE HAS GREATER PERIMETER IN THIS CASE
