Question

The width of a rectangle is 5 3/4 inches. The length is three times its width. What is the perimeter?

Answer 1

perimeter=46.5 inches

Explanation:

`width=2(3)/(4)`

`=(5*4+3)/(4)`

=
`=(23)/(4)`

`length=3((23)/(4) )`

`=(23*3)/(4)`

=
`(69)/(4)`

perimeter of rectangle =2(l+b)

`=2((69)/(4) +(24)/(4) )`

`=2((69+24)/(4) )` (since their denominator are same u can add their numerator)

`=2((93)/(4))`

`=(93*2)/(4)`

`=(186)/(4)`

`=46.5` inches
