Question

A rectangular room has an area of 308 square feet. The length of the room is 8

feet more than the width of the room. Find the length and width of the room, in feet,

Answer 1

x * (8 + x) = 308

8x + x^2 = 308

x^2 + 8x - 308 = 0

x = 14 (because it's impossible for the side to be -22 lol)

now we check (very important)

14 * 22 = 308
