Question

Using Products of Linear Expressions in the Real World
A square garden is expanded to a rectangle in which the width is 1.5 times the original side length and the length is 3.5 times the original side length. The area of the expanded garden can be modeled by the expression (1.5s)(3.5s).

Simplify the expression (1.5s)(3.5s).

5s
5s2
5.25s2
5.25s

Answer 1

(1.5s)(3.5s) = (1.5·3.5)s^2 = 5.25s^2.

So the correct choice is 5.25s2 (i.e., 5.25s^2).
