What is the area of a trapezoid with bases of 15.8 yd and 21.8 yd and a height of 11.7 yd?
439.92 yd2
219.96 yd2
127.53 yd2
92.43 yd2

Add the bases together, divide that by 2 then multiply by the height.

15.8 + 21.8 = 37.6

37.6/2 = 18.8

18.8 x 11.7 = 219.96 yd^2

B) 219.96 yd2

Step-by-step explanation:

The formula for finding the area of a trapezoid is:

(a + b) /2*h

Now you would plug in the numbers

(15.8 + 21.8) /2*11.7

Now solve this in order of operations

(15.8 + 21.8) /2*11.7

37.6/2*11.7

18.8*11.7

219.96

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

there are infinitely many solutions.
