Question

Solve for x perimeter of the rectangle is 100to x - 8 + x + 4 + 2x - 8 + x + 4 = 100 solve for x

Answer 1

The perimeter of rectangle is 100.

The formula for the perimeter of rectangle is

`P=2(l+w)`

The length of the rectangle is 2x-8 and width of the rectangle is x+4.

The perimeter is

`100=2(2x-8+x+4)`
`50=3x-4`
`3x=54`
`x=18`

Hence the value of x is 18.

The length is

`2*18-8=36-8=28`

The width is

`18+4=22`

The correct options are 22 and 28.
