Question

Solve the application problem. Tina decided to build a pen for her new puppy. She decided the length of the pen would be 7 feet and the width would be 4 feet. What will be the perimeter of the new pen? 23 feet 22 feet 28 feet 23 feet

Answer 1

The rule of the perimeter of the rectangle is

P = 2(length + width)

Since the length of it is 7 feet

Since the width of it is 4 feet

Substitute them in the rule above

P = 2(7 + 4)

P = 2(11)

P = 22

The perimeter of the new pen is 22 feet

Answer B
