The sides of the rectangle are 15 cm and y cm. Write the expression for calculating the perimeter of the rectangle. Find the perimeter if y is 10; 1.
The perimeter of a rectangle is the sum of the lengths of all its sides. The rectangle has two sides 15 cm long and two sides y cm long.Let’s write the perimeter of the rectangle:
P = 15 + y + 15 + y = 30 + 2y.
Determine the perimeter if y is 10:
P = 30 + 2 * 10 = 50 centimeters.
Determine the perimeter of the rectangle if y is 1:
P = 30 + 2 * 1 = 32 centimeters.
