Question

the British Thermal Unit(BTU) is a unit of energy used globally in air conditioning industries. the number of BTUs needed to cool a room depends on the area of the room. to find the number of BTUs recommended for any size room room, use the formula B=377lw, where B is the number of BTUs, l is the length of the room, and w is the width of the room. the room you want to cool uses the recommended number of 12,252.5 BTUs and is 5 meters wide. find the area of the room

Answer 1

32.5 m^2

Explanation:

B = 377lw

I will use L for length instead of l.

B = 12,252.5 BTU

w = 5 m

First, we find the length.

12,252.5 = 377(L)(5)

12,252.5 = 1885L

L = 6.5

The length is 6.5 m. The width is 5 m.

A = LW = (6.5 m)(5 m) = 32.5 m^2
