What will be the area of 4 metres high wall on all four sides of a rectangular hall having perimeter 64 m ?
Answer & Solution
Correct Answer:
Option
A
Perimeter = 64 m
⇒ 2(l + b) = 64
∴ Area of 4 walls
= 2(l + b) × h
= (64 × 4) m2
= 256 m2
⇒ 2(l + b) = 64
∴ Area of 4 walls
= 2(l + b) × h
= (64 × 4) m2
= 256 m2
