Answer:
Width=12 inches
Length=15 inches
Step-by-step explanation:
Let's say the width is x.
Then, the length is x+3.
The area of a rectangle is the length times width, so
x(x+3)=180
x^2+3x=180
x^2+3x-180=0
After using the quadratic formula, x comes out to be 12 or -15.
x cannot be -15 because you can't have negative distance, so we are left with x=12.
The width is 12 inches and the length is 12+3=15 inches.
Check: 12*15=180
Answer:
The width is 12 and the length is 15.
Step-by-step explanation:
You set the equation as x is equal to the width and since the lenght is 3 units longer than the width, it can be seen as "x + 3"
[tex]Area=(Length)(Width)[/tex]
180= x × (x + 3)
Then from there you just solve for x.
