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 answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
