added to each side?
5 ft x
10 ft

2 feet

Step-by-step explanation:

Let

x ----> the uniform amount added to each side

we know that

The algebraic expression that represent this situation is

solve for x

Apply distributive property

solve the quadratic c equation

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

therefore

The solution is x=2 ft
