What is the formula for the area of a rectangle? The formula for the area of a rectangle is the product of the length and width of the rectangle. The area of a rectangle is in square units. How do we calculate area? The area of a rectangle is calculated using the formula for the ...
A trapezoid is a quadrilateral that has two parallel sides and two non-parallel sides. The parallel sides are called the trapezoid bases, and the other two are the lateral sides. The trapezoid height is the distance between the lines on which the bases of the trapezoid lie, any common perpe...

The area of a trapezoid can be calculated if the length of its parallel sides and the distance (height) between them is given. The area of a trapezoid with bases are 'a' and 'b' and height is 'h' is A = ½ (a + b) h. Learn this formula with proof and e

There is an easy—and beautiful proof of this. Remember the formula for the area of a triangle: A=b⋅h/2A=b⋅h/2, and now take your irregular trapezoid, a pair of scissors, and cut! If you cut on the line connecting one of the angles to the midpoint of the opposite leg, yo...
