If the area of a rectangle is equal to 70.
Calculate the perimeter of the rectangle.
Given that in a rectangle every pair of opposite sides are equal to each other, we can state that:
Now we can calculate the perimeter of the rectangle by adding all the sides together:
34
Look at the rectangle below.
Side DC has a length of 1.5 cm and side AD has a length of 9.5 cm.
What is the perimeter of the rectangle?
Perimeter means the distance around the shape, so you walk along each side and add up the distances. Area is the space inside, which uses multiplication.
It doesn't matter for perimeter! Whether you call 10 the length or width, you still have two sides of 10 and two sides of 7, giving the same perimeter of 34.
Absolutely! . This is often faster than adding all four sides individually.
The perimeter stays the same! No matter how you orient the rectangle, the sides are still 10 and 7, so the perimeter is always 34.
Check that opposite sides are equal and your arithmetic is right. For this rectangle:
