Answer:
42 square centimeters
Step-by-step explanation:
The total of sides FA and AB will be half the perimeter of the rectangle, or 14 cm. Since AB is 9 cm, that means FA is 5 cm.
EF is the difference between EF and FA, so is 11 cm -5 cm = 6 cm.
FC is the same 9 cm length as AB, so we have enough information about the trapezoid to use the area formula:
A = (1/2)(b1 +b2)h
A = (1/2)(9 cm +5 cm)(6 cm) = 42 cm^2
The area of the trapezium is 42 cm^2.
My vote would be b. because generally when we are figuring area of a room, we are working with materials that are not exact and we usually round off .75 to the next foot. (I have experience in flooring!)
I am sure there are situations where you would want it to be exact however, such as using VERY expensive materials to cover.
The lower ratio would be bob and that dude need to slow down the hair stuff
10 to 8 ratio is about 8.00
7 to 6 ratio is about 9.00
im not to good at math so dubble cheek just in case hope i could help tho
rip my spelling

The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0
<h3>How to determine the axis of symmetry?</h3>
The equation is given as:
y = 2x^2 + 3
Differentiate the above equation with respect to x
y' = 4x + 0
This gives
y' = 4x
Set the equation to 0
4x = 0
Divide both sides by 4
x = 0
Hence, the axis of symmetry is x = 0
