Step 1
Calculate the perimeter of any figure is an easy thing to determine. In order to be able to get the perimeter of either a triangle or a rectangle all you need to do is know the length of all of the sides of the figure and then add all of these numbers together in order to get the perimeter. The perimeter is the sum of all of the sides of a figure to get one length.

Step 2
Determine the area of a rectangle is a calculation in which you will need to use multiplication. To come up with the total area of a rectangle you will need to know the length of the rectangle as well as the width of the rectangle to get the right answer. You will then multiply the length times the width, which will provide you with the total area in square units and denoted as units squared such as miles or inches.

Step 3
Know the area of a triangle is a more complex calculation for you to solve. In this calculation, you will need to know what the height of the triangle is as well as what the length of the base is. In a right triangle, the height and base are the lengths of the two legs that make up the right angle where as with any other triangle the height is a straight line that you draw from one angle to the opposite leg forming a right angle, the length of this line is your height, the leg it intersects will serve as the base. Once you have the height and the base, you will multiply these two numbers together and then multiply them by one-half.

Step 4
Use these two calculations for area to find the area of any figure that has straight sides. You will simply need to break the figure up into rectangles and triangles, determine the area of each and then add them together.
