calculate the height
A trapezoid has an area of 315 square centimeters.
The two base lengths are: a is 24 centimeters and c is 18 centimeters.
Calculate the height of area!
answer:
A = (a + c) * h : 2
315 = (24 + 18) * h : 2 / * 2
630 = 42 * h / : 42
h = 15 cm
A: The height h of the trapezoid is 15 cm.
