Perimeter of Compound Shapes P=Find the perimeter++ 3 + 5 + 10 + 7 =1. Find the missing sides first (the red one and the blue one)2. To find the length of the red side,look at the numbers in orange boxes.All you have to do to find the length ofthe red side is to subtract 10-3=7cm3. To find the length of the blue side,look at the numbers in brown boxes.All you have to do to find the length ofthe blue side is to subtract 7-5=2cm4. Now just add all the sides togetherto find the perimeter of this shape.cm P=Find the perimeter++ 3 + 10 + 6 + 7 =1. Find the missing sides first (the red one and the blue one)2. To find the length of the red side,look at the numbers in orange boxes.All you have to do to find the length ofthe red side is to subtract 10-73. To find the length of the blue side,look at the numbers in brown boxes.All you have to do to find the length ofthe blue side is to subtract 6-34. Now just add all the sides togetherto find the perimeter of this shape.cm P=Find the perimeter++ 2 + 20 + 8 + 11 =1. Find the missing sides first (the red one and the blue one)2. To find the length of the red side,look at the numbers in orange boxes.All you have to do to find the length ofthe red side is to do some subtraction3. To find the length of the blue side,look at the numbers in brown boxes.All you have to do to find the length ofthe blue side is to do some subtraction4. Now just add all the sides togetherto find the perimeter of this shape.cm P=Find the perimeter++ 3 + 7 + 6 + 13 =1. Find the missing sides first (the red one and the blue one)2. To find the length of the red side,look at the numbers in orange boxes.All you have to do to find the length ofthe red side is to do some subtraction3. To find the length of the blue side,look at the numbers in brown boxes.All you have to do to find the length ofthe blue side is to do some subtraction4. Now just add all the sides togetherto find the perimeter of this shape.cm P=Find the perimeter++ 7 + 13 + 9 + 9 =1. Find the missing sides first (the red one and the blue one)2. Then just add up all the sides togetherin order to find the perimeter of this shape.cm
