Question

A rectangle has width w and its length is 3 units shorter than 5 times the width, or 5w - 3. Write a polynomial for the area of the rectangle.

Answer 1

Width = w
Length = 5w-3

Area = (width)*(length)
Area = w*(5w-3)
Area = w*5w + w*(-3) .... distributive property
Area = 5w^2 - 3w

Answer: 5w^2 - 3w
