Use the formula for the area of a trapezoid A=h(b1+b2/2) , where A is area, b1 and b2 are the length of the bases, and h 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?
To find the area of the trapezoid, we need to substitute the given values into the formula.
A = h(b1 + b2)/2
A = 75(125 + 81)/2
A = 75(206)/2
A = 15450/2
A = 7725 square feet
Therefore, there are 7725 square feet of grass on the trapezoidal field.
To find the area of the trapezoidal field, we can use the formula for the area of a trapezoid: A = h(b1 + b2)/2.
In this case, the height (h) of the field is 75 ft, and the lengths of the bases (b1 and b2) are 125 ft and 81 ft, respectively.
Let's substitute these values into the formula to find the area of the trapezoidal field:
A = 75(125 + 81)/2
First, let's simplify the expression inside the parentheses:
A = 75(206)/2
Now, let's multiply 75 by 206:
A = 15,450/2
Finally, let's divide 15,450 by 2:
A = 7,725
So, there are 7,725 square feet of grass on this trapezoidal field.
