Area in square units = 0.5*(sum of parallel sides)*height
Area of a trapezoid in square units = 0.5*(sum of parallel sides)*height Perimeter = sum of its 4 sides
___________ /___________/ Not a very accurate diagram, but you might get the picture. There are 360 degrees in a trapezoid, same as for a rhombus, square and rectangle, or any 4-sided shape (withstraight edges)360 degrees, the same as for any quadrilateral.
Perimeter = sum of lengths of sides.
Area = 0.5*(sum of parallel sides)*height
The sum of all the interior angles is 360 degrees.
Sum_interior_angles = (number_of_sides - 2) x 180o → number_of_sides = sum_of_interior_angles ÷ 180o + 2 = 1800o ÷ 180o + 2 = 12
The sum of a [single] square equals the square.
It's not. Take 49 and 16 for example. The square root of the sum is the square root of 65. The sum of the square roots is 11.
The angle sum of a square is 360.
