To find the area of a trapezoid, we need to know the formula. The formula for the area of a trapezoid is: A = (a+b)h/2, with a and b being the lengths of the bases and h being the height of the trapezoid.
In this particular case, we need to figure out the heights and base lengths, then we can input the values and solve.
The height is 7 yards (because it's the line that makes a right angle when it goes down), and the bases are 4.7 yards and 9.5 yards. Now we can input these values into our formula. The formula becomes:
A = (4.7 + 9.5)*7/2
A = 14.2 * 3.5
That means that our answer is A = 49.7 yd.², or A.
