Question

The length of a rectangle plus its width is 25

cm. The area is 150 square cm. What are the
length and width of the rectangle?
Separate the answers with a comma.

Answer 1

length + width = 25cm
length = 25cm - width
length x width = 150 cm^2
(25cm-w)w= 150
25w-w^2=150
0=w^2-25w+150
0=(w-15)(w-10)
w=10cm
l=15cm
