Answer:
b = ft
Perimeter = 42.6 ft
Explanation:
We know that the area is equal to length times width, so in our case
Area = b x a
Since we know the value of the area and the width we can find the length by doing the following...
Area = b x a
b = Area / a
b = 111.6 / 9.3
b = 12 ft
Perimeter = 2b + 2a
Perimeter = 2(12) + 2(9.3)
Perimeter = 42.6 ft
