Answer:
Easy
Step-by-step explanation:
To find the perimeter, add all the sides together.
12+16+20=48
To find the area, you multiply the sides that make the right angle of the triangle,
12×16=192
And divide it by two. This step is important as if you don't divide it by two, you will end up with the area of a square.
192÷2=96
Finito. Oh and don't forget to add units.
Cm for perimeter and Cm(squared) for area. :)
What is this supposed to be? Is there any actual question?
