Question

The diagram shows a sketch of John's yard. He wants to plant grass, so he must calculate the area of the yard. The distance from A to B is 200 feet; the distance from C to D is 260 feet, and the straight line distance between AB and DC is 220 feet. The area of the yard is
A) 5,720,000 square feet
B) 25,300 square feet
C) 50,600 square feet
D) 57,200 square feet

Answer 1

The area of the yard is 50,600 square feet.

Option: C.

Step-by-step explanation:

The given information forms a trapezoid.

The AB is the upper base (a) and its length is 200 feet.

The CD is the lower base (b) and its length is 260 feet.

A straight line distance from AB and CD is the height (h) and its measures as 220 feet.

The area of trapezoid A= $\frac{a+b}{2} (h)$.

A= $\frac{200+260}{2} (220)$.

=$\frac{460}{2}(220)$.

=230(220).

=50600 $ft^2.$

Thus the area of John's yard is 50,600 square feet.
