Can you calculate the area if you know the perimeter?
No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.
How do you find the area or perimeter of composite figures?
Not easily. You need to find the area or perimeter of the components and sum them.
How do you find the perimeter of a triangle when the perimeter is 177?
If you know the perimeter, there is no need to find it again.
How do you find the perimeter of a scalene triangle when you only know two sides and the area?
To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.
How do you convert perimeter into square meters?
Well, honey, first you need to know the shape you're dealing with to calculate the perimeter. Once you've got that number, you can't just wave a magic wand and turn it into square meters. Perimeter is measured in linear units, while square meters measure area, so you'll need more information to make that conversion.
