Question

Perimeter of a rectangle is 1300 mil

Width is 110 mill less than the length
Find length and width

Answer 1

The length is 380 mill and the width is 270 mill.

Explanation:

Given:

Perimeter of a rectangle is 1300 mil .

Width is 110 mill less than the length.

Now, to find the length and width.

Let the length be
`x.`

Thus, the width =
`x-110.`

Perimeter = 1300 mil.

Now, to get the length and width of rectangle by putting formula:

`Perimeter=2(length+width)`

`1300=2(x+(x-110))`

`1300=2(x+x-110)`

`1300=2(2x-110)`

`1300=4x-220`

Adding both sides by 220 we get:

`1520=4x`

Dividing both sides by 4 we get:

`380=x`

`x=380\ mill.`

The length = 380 mill.

Thus, the width =
`x-110=380-110=270\ mill.`

Therefore, the length is 380 mill and the width is 270 mill.
