Question

The length of a rectangle is six times its width.
If the area of the rectangle is 150in^2, find its perimeter.

Answer 1

draw a picture and label the sides, using the given information



next form the area equation

\[x \times 6x = 150\]

will 6x^2 = 150, x^2 = 25 only consider the positive value

x = 5... width is 5 length is 30...

this should be enough to find the perimeter
