Question

Mr. Glidden is expanding the size of his garden. His new garden will be 3 times as long and 2 times as wide as his original garden. The perimeter of his original garden is 30 feet and the length is 11 feet. What will be the perimeter, in feet of his new garden?

Answer 1

Method One:

Step One: Figure out how long the width is, witch is 19 feet.

Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide

Step Three: Add 38+33

The new perimeter will be 71 feet.
