Question

A rectangle field has an area of 300 square meters and a perimeter of 80 meters. What are the length and width of the field?

Answer 1

It would be 30 and 10
10 is the width
30 is the length

Answer 2

l + w = 40, lw = 300

l(40 - l) = 300

40l - l² = 300

l² - 40l + 300 = 0

(l - 30)(l - 10) = 0

l = 30, w = 10

The length of the field is 30 meters, and the width of the field is 10 meters.
