area of parallelograms and triangles calculator
What is the formula for a parallelogram and a triangle?
The formula to find the area of a triangle is A = 1/2 b x h, where b is the base of the triangle and h is the height of the triangle taken at its highest point.
The formula to find the area of a parallelogram is the same as the formula to find the area of a rectangle, where A = b x h.The area of a parallelogram can be calculated without the height when the length of adjacent sides and the angle between them is known.
The formula to find the area for this case is given as, area = ab sin (θ), where 'a' and 'b' are lengths of adjacent sides, and, θ is the angle between them.
What is the area formula of a parallelogram?
Intuition for why the area of a parallelogram is A = b h
The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.
