Answer:

50 m

Step-by-step explanation:

The area (A) of a trapezoid is found using the formula

A = [tex]\frac{1}{2}[/tex] h(a + b)

where h is the width and a, b the length of the bases

here a = 50, b = 10 and A = 1500

1500 = [tex]\frac{1}{2}[/tex]h(50 + 10) = [tex]\frac{1}{2}[/tex]h × 60 = 30h

divide both sides by 30

50 = h

The width is 50 m
