Question

The perimeter of a rectangle is 15x+17y. if the length is 7/2x+7y, then find the width of the rectangle

A.) 4x+3/2y
B.) 8x+3y
C.) 8x+10y
D.) 4x+3y

Answer 1

A

Explanation:

Length :
`(7x)/(2) + 7y`

Perimeter:
`15x + 17y`

Perimeter = 2(Length + Width)

15x + 17y = 2(
`(7x)/(2) + 7y` + Width)

15x + 17y = 7x + 14y + 2(Width)

15x + 17y -7x -14y = 2(Width)

8x + 3y = 2(Width)

Width =
`(8x + 3y)/(2)`

Width = 4x + 3y/2
