# x-intercept and the y-intercept

1.

The area of a trapezoid is given by

A=1/2h (a+b)

where h is the height of the trapezoid, and a and b are the lengths of the upper and the lower base, respectively.

Solve for a.

2. The length of a rectangle is four times its width. If the area of the rectangle is 196m (m has a 2nd power) , find its perimeter.

3. The perimeter of a rectangular field is 256 yards. If the width of the field is 55 yards, what is its length?

1.

The area of a trapezoid is given by

A=1/2h (a+b)

where h is the height of the trapezoid, and a and b are the lengths of the upper and the lower base, respectively.

Solve for a.

Solution:

2A/h = a + b

=> a = 2A/h - b

2. The length of a rectangle is four times its width. ...

#### Solution Summary

The expert finds both the x-intercept and the y-intercept of the line.
