Question

Henry uses three 10 cm by 5 cm sheets to make the following rectangle:
What is the perimeter of Henry's rectangle?
cm

Answer 1

The perimeter is the distance around an object.

We can find the perimeter by adding all of the edges. Only the outside edges are considered for the perimeter.
The perimeter of Henry's rectangle $=10+10+10+5+10+10+10+5$
$=70$ cm

Hence, the perimeter of Henry's rectangle is 70 cm.
