Answer 1

9000sq2

Explanation:

To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

30 x 40 x 15

without calculator this is 3 x 4 x 1 = 12 then add 000 = 12000 add 5 x 4 x 3 = 60 and add this to the 2nd (single) thousandth number = 18000 when multiplying in a grid.

Then divide by 2

18000/2 = 9000
