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
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.
