Answer:
b = 20 ft
Explanation:
The area of a parallelogram is given by:
A = b*h
where,
A: area = 120 ft^2
b: base = ?
h: height = 6 ft
From the equation for A, solve for b, replace the values of A and h and simplify:
b = A/h
b = 120ft^2/6ft
b = 20ft
Hence, the length of the base of the parallelogram is 20 ft
