Add the lengths of any two adjacent sides, and double the sum.
Yes any polygon that has 4 sides is a quadrilateral.
The spelling is parallelogram (quadrilateral with two sets of parallel sides).
All parallelograms have four sides - it's their defining characteristic.
A parallelogram with all sides equal is a rhombus. Also, if it has one right angle inside, then it's a square.
-- Find out the population of the area. -- Find out the area of the area. -- Divide the population by the area. The result is the population density of the area.
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
To find the perimeter you add and to find the area we multiply.
You can find the area of a diamond shape similarly to the way you find the area of a square except using the diagonals. All you have to do is multiply the diagonals to find the area.
How do you find the area of an unequal quadrangle?
