Answer:
220 squared units
Step-by-step explanation:
first, find the area of the rectangle by multiplying 8 by 20. Then, fin the area of the triangle by multiplying 6 by 20 and then dividing the result by 2.
8*20=160
6*20=120
120/2=60
Finally, add them together and you get 220 units squared.
Answer:
See explanation
Step-by-step explanation:
Given the function f(x) for which
If you want to plot the corresponding points for the inverse of the function f(x), change 
into 
:
switch x and y
and then change into 
You get
Now plot these points on the coordinate plane (see attached diagram).
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
