Rectangle ABCD contains three other rectangles inside it.
Calculate the perimeter of ABCD.
Since in a rectangle every pair of opposite sides are equal to each other, we can claim that:
Now we can calculate side CD:
Since side CD is equal to side AB, it is also equal to 14
Let's calculate the perimeter of rectangle ABCD:
42
Look at the rectangle ABCD below.
Side AB is 6 cm long and side BC is 4 cm long.
What is the area of the rectangle?
Look at the diagram carefully! Side CD is divided into two parts: CF (which equals 9) and FD (which equals 5). So CD = CF + FD = 9 + 5 = 14.
In a rectangle, opposite sides are equal and parallel lines cut by parallel lines create equal segments. Since the internal rectangles align perfectly, corresponding segments are equal.
Use the rectangle property! Once you find one complete side length, the opposite side has the same length. You only need to find the length and width to calculate the perimeter.
Yes! For any rectangle: Perimeter = 2(length + width). The key is correctly identifying what the full length and width are from the given segments.
Your perimeter should be greater than twice the longest measurement you can see. In this case, since we see 9, 7, and 5, a perimeter of 42 makes sense!
