Trapezoid is a four-sided figure with unequal bases. Only two of its sides are parallel. Its area is calculated through the equation,
                           A = MH
where A is area, M is median, and H is height. 

Median is calculated by the getting the average of the bases.
                        M = 0.5(b₁ + b₂)
Substituting the given,
                        M = 0.5(15 cm + 8 cm) = 11.5 cm

The equation for the value of H,

                          H = A/M
                          H = 46 cm²/(11.5 cm) = 4 cm

Answer:

4cm

Step-by-step explanation:

Area= 1/2(b1 +b2)(h)

46 = 1/2(8+15)(h)

46 = 1/2(23)(h)

46/11.5=11.5h/11.5

4 = h
