Type the correct answer in the box.
3 units
units
9 units
3 units
21 units
the area of the figure is
square units.

Area of the figure = 132 Sq. units

Step-by-step explanation:

Area of the figure = Area of triangle 1 + Area of Rectangle 1 +Area of rectancle 2 + Area of triangle 2

     Area of traingle 1:

Base = 9-3 = 6 units

Height =8 units

Area = bh/2  = 6 * 8 /2 = 3 * 8 = 24Sq.units

Area of Rectangle 1:

Length = 8 units

Width = 3 units

Area  = Length * Width = 8 * 3 = 24 Sq.units

ARea of Rectangle 2:

Width = 21 -(9 +3) = 21 - 12 = 9 units

Length = 8 units

Area  = Length * Width = 9 * 8 = 72 Sq.units

Area of Triangle2:

Base = 3 units

Height =8 units

Area = bh/2  = 3 * 8 /2 = 3 * 4 = 12 Sq.units

Area of the figure = 24+24+72+12 = 132 Sq.units
