A trapezoid has an area of 95 square meters. If the bases are 7 meters and 12 meters what is the height of the trapezoid
Colt1911 [192]

ANSWER

The is 10 is meters

EXPLANATION

The area of a tra-pezoid can be calculated using the formula;

Area= \frac{1}{2} \times  (sum \: of \: bases) \times height

We substitute the values to get,

95= \frac{1}{2} \times  (7 + 12) \times height

2 \times 95= 19 \times height

\frac{190}{19}  = height

height = 10

The height is 10 meters.
