Which figure, the purple one, or the dotted one?
Or is it the whole thing?
I got the area I just need the perimeter.
I am trying to figure out which perimeter you need. |dw:1438403519252:dw|
It seems like you are missing one side in order to find the perimeter then.
You need to use the Pythagorean theorem.
The figure is the shaded section. the perimeter is the sum of the lengths all around. yes you need to find the other length first by using Pythagorean theorem.
as i think because the formula is a+b+c
the area is 58.5yd^2
to the nearest tenth means to one decimal place. calculate to 2 places then round.
is it 452
thank you all so much for your help.
do you have the area because you should use Hero's formula?
yes i said it was 58.5yd^2
I know you said that! I am asking why? there are different ways to do a particular problem.
okay thank you
you are welcome
