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.

00:06 Let's determine the perimeter of the rectangle.

00:10 The perimeter is the total length around the rectangle. Add up all the sides.

00:15 Remember, in a rectangle, opposite sides are equal.

00:22 Now, plug in the given values, and calculate the perimeter.

00:26 Great job! That's how we find the perimeter.

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

$AB=CD=10$

$AC=BD=7$

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

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