Answer:
2677 mi^2
Step-by-step explanation:
Think the shape as an complete rectangle :
The area of the rectangle is calcluated by multiplying height*width
(24+12+19)*55 = 3025 mi^2 now subtract the area of the missing part using same area calculation method:
12*29 = 348 mi^2 the area of the figure:
3025 - 348 = 2677 mi^2
You just need to multiply the length with the ratio
for example, if the ratio is :2w : 3L , the actual width would be 2/3 x 27
= 18 cm
