Question

Area of four walls of a room is 91 cm2 if the room is 13 m long and 4.5 m broad find its height

Answer 1

Solution :

Dimensions of the room:

Length (l) = 13 m,

breadth (b) = 4.5 m

Let the height = h m

Area = 91 m²

=> 2(l+b)h=91

=> 2[13+4.5]×h = 91

=> 2 × 17.5 × h = 91

=> h = 91/35

=> h = 2.6 m

Therefore ,

Height of the room (h) = 2.6m
