Rectangle has length(3x-8)and width(2x-7)cm.write down and simplify an expression for the perimeter of the rectangle?

The perimeter of a rectangle is given by the formula P = 2(l + w), where l is the length and w is the width.

Given that the length is (3x-8) cm and the width is (2x-7) cm, the expression for the perimeter of the rectangle is:

P = 2((3x-8) + (2x-7))
P = 2(3x-8 + 2x-7)
P = 2(5x-15)
P = 10x - 30

Therefore, the simplified expression for the perimeter of the rectangle is 10x - 30 cm.

Perimeter of rectangle=2(length+width)
=2[(3x-8)+(2x-7)]
=2(5x-15)
=10x-30
