9. Determine the perimeter and area after removing a square

A square of side 4 $cm$ is cut from the base of the U - shaped figure. The measurements of the sides of the figure after removing the square are $a=$ 4 $cm$, $b=$ 18 $cm$, $c=$ 15 $cm$, $d=$ 4 $cm$, $e=$ 14 $cm$, $f=$ 4 $cm$, $g=$ 14 $cm$, $h=$ 11 $cm$, and $i =$ 14 $cm$.

Find the perimeter and area of the $U$ - shaped figure after removing a square from it and determine the impact on removing the square.

 

 

1.Perimeter of the $U$ - shaped figure $=$  $cm$.

 

2. Perimeter of the $U$ - shaped figure after removing the square $=$  $cm$.

 

3. Area of the $U$ - shaped figure $=$  $sq. \ cm$.

 

4. Area of the $U$ - shaped figure after removing the square $=$  $sq. \ cm$.

 

5. Choose the correct statement.
