Area of a parallelogram
Area of a parallelogram
A parallelogram has two pairs of parallel equal opposite sides. It has a base and a height which is the perpendicular distance between the base and its opposite parallel side.
Area of a parallelogram
Area of a parallelogram is found by taking a triangle and relocating it such that parallelogram becomes a rectangle whose area = l × w
Effectively the length l is the base b of the parallelogram and width w is the height h of the parallelogram.
Formula to find area of a parallelogram
Area of parallelogram is = base × height = b × h
Find the area of the following parallelogram.
Solution
Step 1:
Area of Parallelogram = b × h; b = base = 4 in; h = height = 42 in.
Step 2:
Area of given parallelogram = 4 × 42 = 168 square in.
Find the area of the following parallelogram.
Solution
Step 1:
Area of Parallelogram = b × h; b = base = 4 in; h = height = 4 in.
Step 2:
Area of given parallelogram = 4 × 4 = 16 square in.
