calculate the bace c
The area of the trapezoid is 210 square centimeters.
A trapezoid has an area of 49 square centimeters.
base a is 8 centimeters and the altitude h is 7 cm
Calculate the base c of the trapezoid!
answer:
answer base c:
A = (a + c) * h
2
49 = (8 + c) * 7 / * 2
2
98 = (8 + c) * 7 / : 7
14 = 8 + c / – 8
c = 6 cm
A: The base c of the trapezoid is 6 cm.
