Question

A rectangular room has an area of 375​ square feet. The length of the room is 10​ feet less​ than the width of the room. How can I find the length and width of the room, in feet?

Answer 1

let x = the width, then x-10 = length

x(x-10)=375

x^2-10x-375=0

You can solve by factoring or quadratic formula to find the

width = 25 and the length = 15
