# how do i find the area of trapezoids and triangles

## Area of a triangle:

Area=(base * height)/2

Area of a trapezoid:
Area=height * (b1 + b2)/2
where:
b1=length of top side
b2=length of bottom side

## To find the area of a trapezoid, you can use the formula:

Area = (base1 + base2) x height / 2

1. First, measure the lengths of the bases of the trapezoid. Let's call them base1 and base2.
2. Measure the perpendicular distance between the bases, known as the height of the trapezoid.
3. Plug the values of base1, base2, and height into the formula. Add the lengths of the bases together, multiply the sum by the height, and divide the result by 2. This yields the area of the trapezoid.

To find the area of a triangle, you can use either of the following formulas, depending on the available information:

1. If you know the base and height of the triangle:
Area = (base x height) / 2

Measure the length of the base of the triangle and the perpendicular distance from the base to the top vertex, known as the height. Plug these values into the formula, and divide the result by 2. This gives you the area of the triangle.

2. If you know the lengths of all three sides of the triangle:
Area = √(s(s-a)(s-b)(s-c))

Measure the lengths of all three sides of the triangle and calculate the semiperimeter, denoted as 's'. Then, use the formula to calculate the area of the triangle.

Note: 'a', 'b', and 'c' represent the lengths of the triangle's sides.

Remember to use consistent units (e.g., centimeters, inches) for all measurements to get accurate results.
