Answer 1

`P=19y+15`

Explanation:

Step one:

Given data

dimension of the rectangle

Width = 8y-1.5

Length = 1.5y+9

Required

The expression to represents the Perimeter

Step two:

the perimeter of a rectangle is expressed as

`P= 2L+2W\\\\P=2(1.5y+9)+2(8y-1.5)\\\\P=3y+18+16y-3\\\\`

collect like terms

`P=3y+16y+18-3\\\\P=19y+15`
