A rectangle has a perimeter of 20 inches and an area of 24 square inches. What are the length and width of the rectangle?
s2008m [1.1K]
Perimeter = 2(L + W) = 20 or L + W = 10

And Area = L x W = 24

So with have the SUM "S" of 2 numbers and te PRODUCT "P' of same numbers, then

we can apply te quadratic equation X² -SX + P

X² - 10X + 24 = 0, solve this equation and you'll find L = 6 in and W = 4in

 or 4 in x 6 in
