Calculate the Perimeter: Finding Border Length in a 2×4×5 Rectangular Diagram

Question

What is the perimeter of the white area according to the data?

00:00 Find the perimeter of the large rectangle

00:04 The entire side equals the sum of its parts

00:08 This is the length of side AD

00:11 In a rectangle, opposite sides are equal

00:21 The entire side equals the sum of its parts

00:24 This is the length of side DC

00:28 In a rectangle, opposite sides are equal

00:38 The perimeter of the rectangle equals the sum of its sides

00:45 We'll substitute appropriate values and solve for the perimeter

00:48 And this is the solution to the question
