Question

A rectangular field is seven times as long as it is wide. If the perimeter of the field is 880 feet, what are the dimensions of the field? A) Write an equation you can use to answer the given question. Let w be the width of the field. Do not solve the equation yet.

Answer 1

16w = 880

Step-by-step explanation:

l = Length of the rectangular field

w = Width of the field

Here, it is given that

7w = l

Perimeter of the rectangular field = 880 ft = P

Perimeter of a rectangle

`P=2(Length+Width)\\\Rightarrow P=2(l+w)\\\Rightarrow 880=2(7w+w)\\\Rightarrow 880=16w\\\Rightarrow 16w=880`

The equation is 16w = 880, if the equation is not solved.
