Question: 1 / 400

What is the formula to calculate the perimeter of a rectangle?

l + b +h

2l + 2b

The formula for calculating the perimeter of a rectangle is adding up all its sides, so option B, 2l + 2b, is the correct answer. Option A, l + b + h, is incorrect because the "h" refers to the height, which is not a side of a rectangle. Option C, 4l + 4b, is incorrect because it would double count each side of the rectangle. Option D, P = 2l + h, is incorrect because it is missing a term for the other side of the rectangle. Remember, the perimeter is the distance around the outside of the rectangle, so all its sides must be accounted for in the formula.
