The correct option is
A 4000 square yards
Length of AB = 50 yards
AB is parallel to CD.
In CD,
Length of CD = 110 yards
Length of EF = 50 yards
CE = FD
We observe, CD = CE + EF + FD
Substituting the values, we get:
110 yards = 2CE + 50 yards
⇒ 60 yards = 2CE
⇒ 30 yards = CE
As CE = FD, CE = FD = 30 yards
To find the area, we can overlap
△BEC above
△AFD.
Now, let us rename the points and analyze the lengths obtained.
Thus, a rectangle is formed with a length of 80 yards and a width (h) of 50 yards.
Thus, the area of the field will be:
Area of rectangle = Length
× Width
i.e., Area of rectangle = 80 × 50 = 4000 square yards
Thus, the area of the field in which Eric can grow maize is 4000 square yards.
