The perimeter of a rectangle is 46 cm, length is 16 cm find the width?

1. Since we know that the perimeter of the rectangle is equal to the sum of twice the length and twice the width, therefore we can substitute the values we have in this formula and calculate what the unknown side in this rectangle is. So, let’s determine what the width of the rectangle is equal to, if from the condition of the problem we know that its perimeter has a length equal to 46 cm, and its length is 16 cm.Let us write the solution:

46 = 2 * 16 + 2 * width;

46 = 32 + 2 * width;

46 – 32 = 2 * width;

14 = 2 * width;

width = 14/2;

width = 7 cm.

Answer: The width is 7 cm.
