The value of the area that Esther's company will carpet is : A = 4750.56 ft².
To determine the value of the area that Esther's company will carpet, the Pythagorean theorem is applied to calculate the apothem and then the formula for the area of a regular polygon, in this case a pentagon, is applied as follows:
L = 48 ft
A=?
Applying the Pythagorean theorem results:
( 24ft)² +a² = (40.8ft)²
The value of the apothem is:
a = 32.99 ft
Formula of the area of a regular polygon ( pentagon) :
A= 6*L*a/2
A = 6* 48ft*32.99 ft/2
A = 4750.56 ft²
The complete statement with its corresponding figure is attached.
