The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.
3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)
This side is the base of the lower rectangle.
The dotted line is the hypotenuse of a right triangle.
Use the Pythagorean theorem to solve.
sqrt(10^2 + sqrt(74)^2) = sqrt(174)
The dotted line = sqrt(174)
A. 7 + 3 x (2 + 4) = 25
7 + 3 x 6 = 25
7 + 18 = 25
25 = 25
B. 8^2 divided by 4 x 8 = 2
64 divided by 4 x 8 = 2
64/32 = 2
2 = 2
C. (16 + 8) - 5 x 2 = 14
24 - 5 x 2 = 14
24 - 10 = 14
14 = 14
For each problem use the basis of the acronym PEMDAS.

Evaluate each step in that order.
Answer:
9 liters of fuel covered 81 km
1 liter of fuel would have covered 81/9 km = 9 km
22 liters of fuel would then cover = 22 * 9 = 198 km.
Step-by-step explanation:
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared
So it's best in this case to separate both shapes so you have a rectangle and a triangle so to solve the area of a rectangle you do
