Rectangle with Area 70: Calculate the Perimeter Using Given Dimensions

Question

If the area of a rectangle is equal to 70.

Calculate the perimeter of the rectangle.

00:00 Find the perimeter of the rectangle

00:03 The perimeter of the rectangle equals the sum of its sides

00:09 Opposite sides are equal in a rectangle

00:16 We'll substitute appropriate values according to the given data and solve for the perimeter

00:20 And this is the solution to the question

Since in a rectangle every pair of opposite sides are equal to each other, we can claim that:

$AB=CD=10$

$AC=BD=7$

Now we can calculate the perimeter of the rectangle by adding all the sides together:

$7+10+7+10=14+20=34$
