Write a problem that involves finding the unknown measure of a side of a rectangle include the solution?

Problem:

The area of the patio of a relative's house is 20 square meters.

The width of the patio is 2 meters.

What is the length of the patio?

Solution:

The area is:

A = (w) * (l)

Where,

w: width

l: long

Clearing l we have:

l = A / w

Substituting values:

l = 20/2

l = 10 meters
