Question

a b) You are running around a rectangular ground of length 42 m and breadth 24 m. How many metres do you cover when you complete 6 rounds around it?​

Answer 1

Answer:

792 m

Step-by-step explanation:

perimeter of a rectangle = 2l + 2b

⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m

Perimeter = 1 round

⇒ 6 rounds = 6 x 132 = 792 m

Answer 2

Answer:

792 m

Step-by-step explanation:

First, calculate the perimeter.

= 2(42 + 24)

= 2(66)

= 132 m

Distance covered

= 132 x 6

= 792 m
