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

Answer:
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
Answer:
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
