Answer:
8.284 × 10^4 m^2
Step-by-step explanation:
The area is the product of length and width:
(5.45·10^5 m)·(0.152 m) = 0.8284·10^5 m^2 = 8.284·10^4 m^2
I can use a chart by numbers them on the chart because I think 4 should be after the 3
The formula for the area of a triangle is 1/2*b*h=a.
1/2*b*14=56
b*14=112
b=8
