Question

The length of a rectangle is 5 cm less than twice it’s width the perimeter of the rectangle is 26 cm' what are the dimensions ?

Answer 1

Width=6 and Length=7

Explanation:

To do this you have to make your own equation
You know that Length is `5` less than twice the width so just write
`2w-5` w being the width
Next you have to know perimeter equation for a rectangle which is `P=2(l+w)`
So plug in since you know P
`26=2(2w-5) + 2w`
Now you have your perimeter equal to your length plus width
`26=4w-10+2w`
`26=6w-10`
`36=6w`
`w=6`
Now you have width to equal `6` and plug into you length equation to find length
`2(6)-5`
`12-5=7`
