Question

How many square feet of grass are there on a trapezoidal field with a height of 75 feet and bases of 125 feet and 81 feet.

I know the formula is A = h( b + b) / 2

A = 75 ( 125 + 81) / 2

A = 75 ( 206 ) /2

Answer 1

Your work so far is correct.

Answer 2

OK, my question is do you divide the 206 and multiply times 75 or multiply 75 times 206 and then divide by 2

Answer 3

it doesn't matter. Either way, answer will be same.

Answer 4

Thanks! y’all are correct so far :)

Answer 5

Divide 206 by 2. Your re-written expression should look something like this: 75[(125+81)/2] you use brackets since we want to work with everything inside and THEN multiply it by 75.
