Rectangle & Square

Finding the area in a rectangle is simple.
Multiply the short side by the long side.
No fancy tricks, just length times width times factor.
Its the same with the square area, multiply the two sides.

Rectangle = Length x Width x 0.025
Square = Length x Width x 0.025

Length = Width =

Circles

For a circle take the radius (that's half the distance across the middle of the circle) and square it.
If the circle is 20 feet across take half of that (10) and multiply it by its self.

Circle's Area = 3.14 x Radius²
For example: 10 x 10 = 100, or 10² = 100, you would now multiply it with 3.14,
which is 100 x 3.14 = 314, therefore the area of a 20 foot circle would be 314 square feet.

Triangles

Right-Angled Triangles are kind of like rectangles, taking calculations form a right angle multiply a x b then divide by 2.
This only works with RIGHT-ANGLED triangles.
That means that one corner has to be square (90º).
Triangle's Area = (a x b) ÷ 2
For example: a = 4 and b = 6, then your calculations would be 4 x 6 = 24
The area of the triangle is half of 24, 24 ÷ 2 = 12

A =   B =
