Question

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

Answer 1

Answer:

             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
