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
I believe that the answer would be C. 1.3 seconds
