A diagram of a room is shown. if the perimeter of the room is 78 feet, qhat is the area of the room

380.25 ft²

Explanation:

perimeter of a room

P = 78 ft

And formula for Perimeter is

P = 4 L (equation no 1)

Put the value of P in equation no 1.

78 = 4 L

L = 78/4

L = 19.5

As we know that if the room is square then it has 4 equal sides.

so the Area will be:

A = L * W

A = 19.5 * 19.5

A = 380.25 ft²
