Part 9: What is the area of this figure? NO LINKS!!

shaded region : 591 square kilometres

Step-by-step explanation:

Area of the whole rectangle = L * W = 32 * 20 = 640 square kilometres

Area of unshaded region = ( 5 * 9 ) + ( 4 * 1 ) =  49 square kilometres

the shaded region = Area of the whole rectangle - Area of unshaded region

                               =        640           -            49

                               =         591 square kilometres

  591 km²

Step-by-step explanation:

Extending the horizontal line divides the figure into three rectangles:

  top: (20-5) × 32

  bottom left: 5 × 19

  bottom right: 4 × 4

The total area is the sum of products of the dimensions of these rectangles:

  A = (15×32 +5×19 +4×4) km² = (480 +95 +16) km² = 591 km²
