This a morning work and I don't get when they say "Area of a triangle" I'm still working on it, but Im just so confused. Can you help?

 B.100

Step-by-step explanation:

20 multiplied by 10 equals equals 200, and 200 divided by 2 equals 100.

(b) 100^2in

Step-by-step explanation: Well 1st area means inside so they wanted you to find the inside,  and well the answer is 100 hope it helped :)

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
