Part a
The area of the figure is equal to the area of two rectangles
Area of the top rectangle
A=(6)*(5)=30 unit2
Area of the bottom rectangle
A=(8)*(4)=32 unit2
therefore
The total area is
A=30+32
Part b
Find out the perimeter
To find out the perimeter adds all the length sides
so
P=8+4+(8-6)+5+6+5+4
