## Why is the formula for the area of a trapezoid? – All you need to know

• ### How does formula for a trapezoid work?

A trapezoid, also known as a trapezium, is a 4-sided shape with two parallel bases that are different lengths. The formula for the area of a trapezoid is A = ½(b1+b2)h, where b1 and b2 are the lengths of the bases and h is the height.
• ### What is the unit for area of a trapezoid?

What is true about the areas of the trapezoids? Each area is equal to half of the area of ABCD.
• ### What is true about the areas of the trapezoids?

It can be determined easily using a formula, A = ?r2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc.
• ### How do you derive area formula?

Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides. It is also called a Trapezium. A trapezoid is a four-sided closed shape or figure which cover some area and also has its perimeter. It is a 2D figure and not 3D figure.
• ### What is true about the areas of the trapezoids?

A trapezoid is a quadrilateral with one pair of parallel sides. Two sides of a shape are parallel if lines placed along them never cross. Parallel. Not parallel. In a quadrilateral, parallel sides must be opposite sides.
• ### What is a trapezoid 3rd grade?

To make a trapezoid, you need a triangle. Any triangle will do: right, obtuse, isosceles, scalene.

The parallel sides are called the bases of the trapezoid. The other two sides are called the legs (or the lateral sides) if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases).
