This is a proportion problem. 25/15 = 90/x . Here you would cross multiply and get the formula 25x = 1350. Divide 1350 by 25 and you get 54.
Hi there! The answer is 15 feet.
The easiest way of solving this problem is by setting up and solving an equation.
Let the length of Howard's patio be represented by X. Now we can get the following expressions
3 times the length of Howard's patio would be 3X (multiply by three).
5 feet less than 3 times the length of Howard's patio would be 3X - 5 (just subtract five).
Now we've found an expression that represents the length of John's patio. Knowing this we can set up and solve an equation.

First add 5 to both sides of the equation.


Finally divide both sides by 3.

Therefore, the length of Howard's patio is 15 feet. The answer is 15 feet.
