Question

A trapezoid has one base equal to its height, $x$, and the other base is twice as long. Write the expression for the area of the trapezoid as a common fraction in terms of________.

Answer 1

The area of the trapezoid is $x$/2(3$x$)

Explanation:

Area of trapezoid (A) = 1/2 (sum of two parallel bases) × height

One of the base = the height = $x$

The other base = 2 × $x$ = 2$x$

A = 1/2 ($x$ + 2$x$) × $x$ = $x$/2(3$x$)
