The perimeter of a rectangle is found by adding up all four sides.
One side has a length of (8c-5) centimeters.
One side has a length of (2c+10) centimeters.
The other two sides are also equal to these lengths.
Therefore, the expression that represents the perimeter is:
(8c-5) + (2c+10) + (8c-5) + (2c+10) = 20c + 10.
So the correct answer is 20c + 10.
The width of a rectangle measures left bracket, 8, c, minus, 5, right bracket(8c−5) centimeters, and its length measures left bracket, 2, c, plus, 10, right bracket(2c+10) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
