The length of a rectangular photo frame is x cm. The width of the frame is 65 cm shorter than 3 times its length. write an algerbraic expression for the perimeter of the photo frame.

Answer 1

The width of the frame is 65 cm shorter than 3 times its length, so the width can be expressed as 3x - 65 cm.

The perimeter of a rectangle is calculated by adding the lengths of all its sides.

The perimeter of the photo frame can be represented by the algebraic expression:

2(length + width)

Substituting the expressions for length and width:

2(x + (3x - 65))

Simplifying:

2(4x - 65)

= 8x - 130 cm
