What is the area of this trapezoid?

18

Step-by-step explanation:

Area = h*(b1+b2)/2

well b1 is 4 and b2 is 8 because 4+4

to find h you need to know pythagorean theorem which is a^2+b^2=c^2

well c is always the longest measurement and directly across from the right angle so in this case it is 5. a is just the base which is for so you can just plug that into a calculator to get b as 3.

b is your height so now you have everything you need to know in order to get the answer

h = 3

b1 = 4

b2 = 8

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

i think it is c, not positive though
