Question

The length of a rectangle is three inches more than the width. The area of the rectangle is 270 inches. Find the width of the rectangle.

Answer 1

Answer:

15inches

Step-by-step explanation:

let width of the rectangle be x inches and length is x+3 inches

area =x*(x+3)=270

x²+3x-270=0

x²+18x-15x-270=0

x(x+18)-15(x-18)=0

x=-18 and 15

since negative values are not being taken into consider then width is 15inches
