Question

The width of a rectangle measures left bracket, 9, v, minus, 3, right bracket(9v−3) centimeters, and its length measures left bracket, 10, v, plus, 10, right bracket(10v+10) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

The expression for the Perimeter of the rectangle is 38v + 14

Using the parameters given for our Calculation;

• width = 9v - 3
• length = 10v + 10

The Perimeter of a rectangle is Calculation using the formula:

• Perimeter = 2(length + width)

Substituting our values into the formula;

Perimeter = 2(10v + 10 + 9v - 3 )

Now we have ;

2(19v + 7)

Perimeter = 38v+ 14

Therefore. the expression for the Perimeter is 38v + 14
