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?

By definition the area of a rectangle is:

A = w * l

The perimeter is:

P = 2w + 2l

Where,

w: width

l: long

Substituting values:

300 = w * l

80 = 2w + 2l

Solving the system of equations we have:

l = 30 m

w = 10 m

Answer:

The length and width of the field are:

l = 30 m

w = 10 m
