How To Calculate The Area Of A Trapezoid
Let s assume that you want to calculate the area of a certain trapezoid All the data given is 30 125 h 6 cm a 4 cm P 25 cm Calculate the remaining internal angles As 180 180 30 150 Similarly as 180 180 125 55 The area of the trapezoid = A = ½ (a + b) h. A = ½ (32 + 12) × (5) = ½ (44) × (5) = 110 cm 2. Area of Trapezoid without Height. When all the sides of the trapezoid are known, and we do not know the height we can find the area of the trapezoid. In this case, we first need to calculate the height of the trapezoid.
Area of a trapezoid is found with the formula A a b h 2 To find the area of a trapezoid you need to know the lengths of the two parallel sides the bases and the height Add the lengths of the two bases together and then multiply by the height The formula for the area of a trapezoid is (base 1 + base 2) / 2 x height, as seen in the figure below: The calculation essentially relies on the fact a trapezoid's area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area.

A hm Derivation Substituting the value for m into the original trapezoid area formula Finding area using a grid Another way to find the area of a trapezoid is to determine how many unit squares it takes to cover its surface Below is a unit square with side lengths of 1 cm The area of a trapezoid is basically the average width times the altitude, or as a formula: Area. = h. ·. b. 1. +. b. 2. where. b1, b2 are the lengths of each base. h is the altitude (height) Recall that the bases are the two parallel sides of the trapezoid.
We ll show you how to calculate the area of a trapezoid how to find the height of a trapezoid or what the trapezoid perimeter formula looks like Also we ll take the time to describe some special types of quadrangles the isosceles trapezoid and the right trapezoid The basic formula to calculate the area of a trapezoid is given below: Area of a Trapezoid. Let us solve an example to understand the concept better. Find the area of a trapezoid whose base lengths are 14 cm and 9 cm, and height is 5 cm. Solution: As we know, Area (A) = ½ (a + b) × h, here a = 14 cm, b = 9 cm, and h = 5 cm. ∴A = ½ (14 + 9) × 5.
