The base of a triangular garden measures 5.5 feet. it takes 33 pounds of mulch to cover the garden. if 4 pounds of mulch are needed to cover a square foot, what is the height of the garden?

f. 1.5 ft

g. 3 ft

h. 4 ft

j. 6.6 ft

The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is

A = 0.5bh

The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:

4A = 33

Substituting A = 0.5*5.5*h = 2.75h to the equation:

4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet
