Answer:
13cm
Explanation:
The area of a trapezoid is given by the formula:
Area = ½*(b1+b2)*h
where:
- b1 and b2 are the lengths of the bases of the trapezoid
- h is the height of the trapezoid
In this problem, we are given that b1 = 6 cm, b2 = 15 cm, and Area = 136.5 square centimeters.
Plugging these values into the formula, we get:
136.5 = ½*(6 + 15)*h
Solving for h, we get:
136.5=10.5h
h = 136.5/10.5=13centimeters
Therefore, the height of the trapezoid is 13 centimeters.
