Your yard is in a shape of a trapezoid

You would tell him 1,425ft².

Step-by-step explanation:

f

First, you need to know the equation for finding the area of a trapezoid, which is ½h(b1+b2) .

When you plug in all the number you have into the equation, you have a new equation essentially that says, ½×30(65+50) .

When you start solving the equation, you need to do parentheses first, so 65+30, which would get you 95. This would then turn the equation into ½×30(95) .

Next, you have to do 30×95, which would come out to be 2850. When you do this, your equation would now be ½×2850 , or essentially 2850÷2 .

When you do the last and final step of the problem, which is ½×2850, you would get 1425. But since it's area, your answer would 1425ft².
