1. triangle + rectangular = (1/2 x 6 x 4) + (6 x 7.5) = 57 ft^2

2. A + B + C = (1/2 x 2 x 3) + (11 x 4) + (1/2 x 3 x 3) = 51,5 ft^2

3. square + rectangular = (2 x 2) + (3 x 6)= 22 m^2

What is the answer I really need help

Answer: 27

Step-by-step explanation:

The perimeter is the lengths of all sides of the figure added together. Since all sides are equal in this triangle, we know all sides have a length of 9. We know this because all sides have 2 little lines on them, symbolizing that they are equal.

Help answer please!!

Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\$

Now we take square root on both sides,

$\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\$

so the value of h equals 19.7 ft.
