How do you get the area of a trapezoid?

To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

Why is the area of a trapezoid?

The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height × (base1 + base2). Because the parallelogram is made from exactly the same “stuff” as the trapezoid, that’s the area of the trapezoid, too.

What is the base of a trapezoid?

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

What is the formula for finding perimeter of a trapezoid?

Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P = a + b + c + d.

What are the sides of a trapezoid?

The parallel sides are called the bases and the non-parallel sides are the legs of the trapezoid. An isosceles trapezoid is a trapezoid in which the two non-parallel sides are congruent .

What is the formula for finding the area for a trapezoid?

Summary: To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2, The formula for the area of a trapezoid is: Where is , is , is height.

How do you find the area of triangle with vertices?

To find the area of a triangle where you know the x and y coordinates of the three vertices, you’ll need to use the coordinate geometry formula: area = the absolute value of Ax(By – Cy) + Bx(Cy – Ay) + Cx(Ay – By) divided by 2.

How do you find the area of regular polygons?

To find the area of regular polygons, use the formula: area = (ap)/2, where a is the apothem and p is the perimeter. To find the apothem, divide the length of one side by 2 times the tangent of 180 degrees divided by the number of sides.

How do you find the area of a triangular base?

Find the area of the base by using the following formula: base area = 1/2 × base side × height. Record this value. Measure all three sides of the triangular base and the height of the prism between its two bases. Record these values.
