Question

The width of a rectangle measures (8.1g-6.5)(8.1g−6.5) centimeters, and its length measures (4.7g-9.2)(4.7g−9.2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

P = (25.6g - 31.4)

Explanation:

Given that,

The width of a rectangle = (8.1g−6.5) cm

The length of a rectangle, = (4.7g−9.2)

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

Substitute all the values,

P = 2(8.1g−6.5+4.7g−9.2)

= 2(12.8g-15.7)

= 25.6g - 31.4

So, the perimeter of the rectangle is equal to (25.6g - 31.4).
