Calculate how many miles in a Km taking the help of easy and handy tool Kilometers to Miles Converter and get the detailed worked out procedure on how to approach.


Enter the value in Kilometers


Result

138 Kilometers is equal to 85.749198 miles

To convert Kilometers to Mile

we know that, 1 kilometer = 0.621371 miles

To convert Kilometers to miles, multiply the kilometer value by 0.621371.

Result in Kilometers: 138 km × 0.621371 × km/mi

Cancel The Comman factor of km

Result in Miles: (138 x 0.621371 mi)

Multiply 138 into 0.621371

Result in Miles: 85.749198 miles

∴ 138 Kilometers = 85.749198 miles

What is Trapezoid?

A Trapezoid is a 4-sided geometrical shape with two sides parallel to each other. And we called these two sides (a and b) as bases of the trapezoid. The other two sides (c and d) are called legs. The height of the trapezoid is represented as 'h'. The height (or altitude) of a trapezoid is the perpendicular distance between the two bases. All internal angles of a trapezoid sum to give 360°. Moreover, the angles on the same side of a leg are called adjacent and always sum up to 180° and it determines in the equations as,

α + β = 180°

γ + δ = 180°

Area of a Trapezoid Formula

The area of a trapezoid is basically the average width times the altitude, or as a formula:

Area = 1/2 * height * (base1 + base2)

where

b1, b2 are the lengths of each base

h is the altitude (height)

Steps to Find the Area of a Trapezoid?

A 4 – sided geometrical figure which has one pair of parallel sides is called a Trapezoid. Most the time the bases are parallel. To find the Area of Trapezoid, all you need to do is just go ahead and implement the steps that are given below:

  1. First of all, note down the given parameters such as side lengths and height.
  2. In the next step, Add the parallel bases i.e., base1 and base2.
  3. Now add the sum of bases and the height of the trapezoid.
  4. Once, the step is completed just divide the result by 2.
  5. Finally, you will get the Area of Trapezoid as an output

For more clarity about how to find the area of a trapezoid, we are going to give the solved example below:

Example:

Find the Area of Trapezoid whose base1 is 23 cm, base2 is 12 cm and height is 6 cm?

Solution:

The given parameters such as base1 b1 = 23 cm, base2 b2 = 12 cm, and height h =6 cm

Substitute the values of the bases (b1 = 23 cm and b2 = 12 cm) and height h = 6 cm into the area of a trapezoid formula

Area = 1/2 * height * (base1 +base2)

Put the value of base and height value in Area Formula.

Area = 1/2 * (6 cm) * (23 + 12) cm

Add the bases value b1 = 23 cm and b2 = 12 cm

Area = 1/2 * 6 cm * (35.0 cm)

Multiply 6 cm and 35.0 cm

Area = 1/2 * 210.0 cm2

Divide 210.0 cm2 by 2

Area = 105.0 cm2

Thus, Area of a Trapezoid whose parameters are 23 cm, 12 cm, and 6 cm is 105.0 cm2
