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

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

Answer 1

either way.

(a*b)/c = (b/c)a = a b / c

Answer 2

thank you

Answer 3

you could easily have verified it on your handy dandy calculator. Can't believe you went to the trouble of posting such an easy thing to check.
