Members of a landscaping company built a retaining wall. The length of the wall is 2 3/4 feet and the width 8 1/2 feet. Estimate the area of the whole retaining wall

Answer 1

To estimate the area of the whole retaining wall, we need to multiply the length by the width.

Converting the mixed numbers to improper fractions, we have:
Length: 2 3/4 feet = (4*2 + 3)/4 = 11/4 feet
Width: 8 1/2 feet = (2*8 + 1)/2 = 17/2 feet

Now, multiplying the fractions, we get:
Area = (11/4) * (17/2) = 187/8

Therefore, the estimated area of the whole retaining wall is 187/8 square feet.
