which unit of measure would be appropriate for the area of a picture that is 20 cm tall and 15 cm wide ?

square centimeters or cm^2

Step-by-step explanation:

area is measured in square units. Since this picture is in cm, it's square cm, because it's length (or height, here) x width.

20 cm x 15 cm = 300 cm^2

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
