Find the area of the figure. Round to the nearest tenth if necessary. Please explain how if you can, this is due tomorrow morning at 9:00

165

Step-by-step explanation:

The formula for finding the area of a trapezoid is (a+b)/2*h

a= longer side

b= shorter side

h=height

Filling in the values:

(21+12)/2*10

21+12=33

33/2=16.5

16.5*10= 165

The area of the trapezoid is 165

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
