length of a rectangle

Question

the length of a rectangle is 5 feet more than 3 times the width. if the area is 22 feet,find the width and the length.

Answer 1

For this problem, you will use the area formula: A=l*w

The question tells us that length is 5 feet more than 3 times the width.

We can use this information to write a formula: l (length)= 5+3w (width)

So we will use substitution to solve with the area formula: 22=(3+3w)*w

Then you will solve for w.

Hope this helps!
