Question

The length and breadth of a rectangular courtyard is 45 m and 35 m respectively. Find the distance covered by a boy to take 5 rounds of the courtyard.

• A. 200 m
• B. 400 m
• C. 600 m
• D. 800 m

Answer 1

The correct option is D 800 m

Given,
Length of the courtyard = 45 m
Breadth of the courtyard = 35 m

Courtyard is in the shape of rectangle.
We know that perimeter of a rectangle = 2 x (length + breadth)
Therefore, perimeter of the courtyard
= 2 (45 + 35) m
= 2 × 80 m
= 160 m

Distance covered by the boy in taking 5 rounds of the courtyard
= 5 × perimeter of courtyard
= 5 × 160
= 800 m
