the formula for the area of a trapezoid is a=1/2h(b1+b2) are the are the length of the bases, and is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?
so, just plug in your numbers!
To find the area of a trapezoid, you can use the formula A = 1/2 * h * (b1 + b2), where A is the area, h is the height, b1 is the length of the first base, and b2 is the length of the second base.
In this case, the height (h) is 75 ft, the first base (b1) is 125 ft, and the second base (b2) is 81 ft.
Now, you can substitute the values into the formula:
A = 1/2 * 75 * (125 + 81)
First, add the lengths of the bases:
A = 1/2 * 75 * 206
Next, multiply 75 and 206:
A = 0.5 * 75 * 206
A = 7725 square feet
So, there are 7725 square feet of grass on the trapezoidal field.
