The length of one base of a trapezoid is 19 less than five times the length of the other base. if the trapezoid has a height of 18 feet an area of 477ft, find the length of the longer base

The length of the longer base is 41 ft.

Explanation

Lets assume, length of one base is ft.

As, another base is 19 less than five times the length of this base, so the length of another base

The trapezoid has a height of 18 ft and area of 477 ft²

Formula for Area of trapezoid, , where = Two bases of trapezoid and = height of the trapezoid.

Given in the question: and

We have also two bases as: and

So, according to the above formula...

So, length of one base is  and another base

That means, the length of the longer base is 41 ft.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

- (2, -7)

- lines r and s and lines t and u must be parallel
