Question

The length of a rectangle plus its width is 24 cm. The area is 143 square cm. What are the length and width of the rectangle?

Answer 1

Let length be L.
Length + Width = 24
L + Width = 24
Width = 24 - L

Area of rectangle = Length x Width = 143
143 = (L)(24 - L)
143 = 24L - L^2

Factorize / do quadratic equation solver to find L.
As you would obtain two values of L, but L > 0 to eliminate one of those values.

Hope this helps.
