The area of this figure is 532m.
First you do the square which is 18 time 18 gets you 324m.
The for the first triangle you would do 18 times 16 then divide by 2 which is 144m.
For the last triangle you would do 16•8 div by 2 which will give you 64m.
Add them all up and you get 532m.
13.63 * 38 = 517.94
671.28 - 517.94 = 153.88
153.88 : 13.63 = 11.25 the number of hours she overworked
Answer:
a) the number of miles in 1 kilometer
Step-by-step explanation:
The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.
So to make the conversion<u> it is enough to know how many miles are in one kilometer.</u>
For example, lets convert 10miles/hour to kilometers/hour.
there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:

Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.
