Answer 1

`(11)/(8)`Answer:

55 in by 40 in

Explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width )

Here l =
`(11)/(8)` y and w = y with P = 190

2y + (2 ×
`(11)/(8)` y ) = 190

2y +
`(11)/(4)` y = 190 ( multiply through by 4 to clear the fraction )

8y + 11y = 760 , that is

19y = 760 ( divide both sides by 19 )

y = 40

Thus l =
`(11)/(8)` × 40 = 11 × 5 = 55 in and w = 40 in
