Question

Because the lid of a marker is wider than the marker itself, a set of markers can be packaged in a container that is in the shape of a trapezoid instead of a rectangle.

A trapezoid has a base of 12 inches, height of 10 inches, and top side length of 10 inches. A rectangle has a base of 12 inches and height of 10 inches.

What is the difference in area between the two packages?
1 square inch
2 square inches
5 square inches
10 square inches

Answer 1

Answer:

A trapezoid has height of 40 in, a base of 15 in and an area of 2400 sq in. What is the length of the other base?

Let the second base be B.

(15+B)*40/2 = 2400 or

15+B = 2400*2/40 = 120, or

B = 120–15 = 105 in.

Check: (15+105)*40/2 = 120*40/2 = 2400. Correct.

The other base is 105 in.
