Question

Scenario:

A rectangular plot of ground is 5 meters longer than it is wide. Its area is 20,000 square meters.

Question:

What equation will help you find the dimensions?

Note: Let W represent the width.

Options:

w(w+5)=20,000
w^2=20,000+5
(w(w+5))/2=20,000
w+2(w+5)=20,000

Answer 1

To find the area you multiply the length by the width.

W = the width, and you are told the length is 5 meters longer, so the length would be (W +5)

Now multiply those together to equal 20,000 square meters:

w(w+5) = 20,000
