Question

Bill needs to edge his yard with the dimensions in the shape below. What area will he have walked after completing his edging? Round your answer to one decimal place. Do not include units in your answer.

Answer 1

37.8

Explanation:

The distance is the addition of all sides of the figure. Then, we need to find the length of the diagonal (d). To do that we have to make a right triangle with height (h) = 5 m. Given that the top length is 12 m and the bottom length is 15 m, the base (b) of the triangle is 15 - 12 = 3 m.

Using Pythagorean theorem:

d² = h² + b²

d² = 5² + 3²

d = √34

d = 5.8 m

Therefore, the distance he will have walked is 5.8 + 12 + 15 + 5 = 37.8 meters
