A cabin was built in the shape of a rectangle. It is 15 meters (m) long and 10 m wide. how far is it all the way around the outside of the cabin?

which of these shows a way to solve the problem?

1 answer

A. Add the length and width together, then multiply by 2
B. Subtract the length from the width, then multiply by 2
C. Subtract the length from the width, then divide by 2
D. Add the length and width together, then divide by 2

The correct way to solve the problem is:
A. Add the length and width together, then multiply by 2

Calculation:
Perimeter = (15 + 10) x 2 = 50 meters

Therefore, the total distance around the outside of the cabin is 50 meters.
