Step-by-step explanation:

Area of parallelogram (a)  = base length (b) * height (h)

Information that is given:

area (a) = 8ft²

height (h) = 2ft

base length (b) = ?

* plug in given information into a = bh and solve for b *

8 = 2b

step 1 divide each side by 2

8 / 2 = 4

2b / 2 = b

b = 4

341

step-by-step explanation:
