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

    32.5 m^2

    Step-by-step 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
