| September 16, 2021 | education
To find the area of a trapezoid, there is a formula:
S = (a + b): 2 * h, where
a and b are the bases of the trapezoid, and h is the height of the trapezoid.
Substitute the given values into the formula:
S = (23 cm + 11 cm): 2 * 7 cm = 34 cm: 2 * 7 cm = 17 cm * 7 cm = 119 cm2.
Answer: the area of the trapezoid is 119 cm2.
