Step-by-step explanation:
Answer:
A. Height of the Flag pole
B. Longest.
Explanation:
Two similar triangles have corresponding sides with the same ratio.
A smaller triangle is showing the shadow of a person and the larger one is showing the shadow of a flag.
Now the person's shadow in the smaller triangle corresponding to the Height of the Flag pole.
The longest side of the large triangle corresponds with the Longest side of the smaller triangle.
The side of the barn is made of 2 shapes, a triangle and a rectangle. Find the area of each shape, then add together to find the total area.
To find the area of the triangle, we multiply 1/2 x (triangle base x triangle height), we can find the triangle height by subtracting the height on the right by the height on the left, so 26.5-14.5 = 12.5ft.
The area of the triangle is 1/2 x (22.8x12.5) = 142.5 square ft.
The area of the rectangle is calculated by multiplying one side by the other, which is 22.8x14.5 = 330.6 square feet.
The total area of the side of the barn is 330.6 + 142.5 = 473.1 square feet.
Since we now know the area of the side of the barn, we can find the cost of paint needed. A one gallon paint can covers 350 square feet and costs $20, but we need to paint 473.1 square feet so we'll need to buy a second can. This means we can easily paint the side of the barn with 2 cans, costing $40 in paint.
