Question

A rectangular vegetable garden will have a width that is 4 feet less than the length, and an area of 140 square feet. If x represents the length, then

the length can be found by solving the equation:
x(x-4)= 140
What is the length, x, of the garden?

Answer 1

17.5

Explanation:

x(x-4)=140

2x=140/4

2x=35

x=35/2

x=17.5

Answer 2

Solving for x would give me 14 and negative 10 which would lead to the problem looking like so 14(-10-4)=140
