Question

A rectangular field is ten times as long as it is wide. If the perimeter of the field is 1430 feet, find the length and width of the field?

Answer 1

below

Explanation:

The steps to solve this are:

The perimeter of a rectangle is given by p=2(l+w) where p is the perimeter, l is the length and w is the width. We are told the length of the field is 10 times the width so l=10w. Using this in the formula above we get:

2090=2(10w+w)

22w=2090

w=95 ft

l=950 ft
