Question

6. The length of a football field is 30 yards more than its width.

Express the length of the field in terms of its width. If the perimeter
of the field is 340 yards. find the width of the field. I

Answer 1

the width be 70 yards

Explanation:

The computation of the width of the field is as follows:

As we know that

The Perimeter of the rectangle is

= 2 × (length + width)

Where

Perimeter is 340 yards

Let us assume the width be x

So, the length would be x + 30

Now put these values to the above formula

340 = 2 × (x + x + 30)

340 = 2 × (2x + 30)

340 = 4x + 60

4x = 280

x = 70

The length would be

= 70 + 30

= 100

Hence, the width be 70 yards
