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= [tex]\frac{a+b}{2} (h)[/tex].
A= [tex]\frac{200+260}{2} (220)[/tex].
=[tex]\frac{460}{2}(220)[/tex].
=230(220).
=50600 [tex]ft^2.[/tex]
Thus the area of John's yard is 50,600 square feet.
