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.
