Question

Write a function rule for the area of a rectangle whose length is 3 more inches than the width.

Select one:

a.
A = LW


b.
A = w2 + 3


c.
A =2 (w + 3) + 2w


d.
A = w2 + 3w

Answer 1

d

Explanation:

The area (A) of a rectangle is calculated as

A = lw ( l is the length and w the width)

let w be width, then length l = w + 3 , so

A = w(w + 3) ← distribute parenthesis by w

= w² + 3w → d
