Answer:
The area of the triangle should be: [(1 + 5 + 4) × 11]/2= 55 (ft²)
The area of the rectangle should be: 5 × 2 = 10 (ft²)
The area of the shaded region is: 55 - 10 = 45 (ft²)
This item is a probability problem.
The question that is asked is that "What is the Probability of being left-handed given that you put on your left shoe, first?"
P (left-shoe) = 20 / 150
P (right-shoe) = 93 / 150
P (right | left-shoe) = 10 / 20
P (left | left-shoe) = 10 / 20
P (right | right-shoe) = 90 / 93
P (left | right-shoe) = 3 / 93
P ( left-handed | left-shoe ) = 10 / 20
Answer/Step-by-step explanation:
a. Unknown side, b, using the Pythagorean theorem is solved as shown below.





Unknown side, b, = 36 km
b. Perimeter of the triangle = sum of all the sides of the ∆ = 

c. Area of triangle = ½*base*height
where,
Base = 36 km
Height = 27 km
