Question

The area of 4 walls of a hall is 266sq. M. The length and breadth of the hall are 12 m and 7m recpectively. Find the height of the wall.

Answer 1

We know ,LSA=2 (l+b)h

=>266=2(12+7)h

=>h×2×19=266

=>h=266/(2×19)=266÷38=7 m

PLEASE MARK IT AS BRAINLIEST.IT'S A HUMBLE REQUEST. PLEASE.

Answer 2

Answer:

Step-by-step explanation:

Area of 4 walls means the lateral surface area of a cuboid that is 2h(l+b)

Therefore,

2h(l+b) = 266

2h(12+7) = 266

2h(19) = 266

38h = 266

h = 7 m
