How do you find the area of a trapezoid shape?
The area of a trapezoid is found using the formula, A = ½ (a + b) h, where ‘a’ and ‘b’ are the bases (parallel sides) and ‘h’ is the height (the perpendicular distance between the bases) of the trapezoid.
How do you find the surface area and volume of a trapezoid?
The surface area of a trapezoidal prism can be given with this formula: (b1+b2)h + PH. In this formula, “b1” and “b2” stand for the length of the bases of the trapezoid. The height of the trapezoid is “h”. The perimeter of the trapezoid is “P”, and “H” is the height of the prism.
Where does the formula for the area of a trapezoid come from?
Explanation: 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.
What is the surface area of a trapezoidal prism?
Answer: The surface area of a trapezoidal prism is h (b + d) + l (a + b + c + d)
What is the equation for the area of a trapezoid?
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(b 1 +b 2 )h, where b 1 and b 2 are the lengths of the bases and h is the height. If you only know the side lengths of a regular trapezoid,…
What is a trapezoid area?
Area is 2-dimensional like a carpet or an area rug. A trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram to the right, the bases are parallel. 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,…
What is the measurement of a trapezoid?
A trapezoid has bases that are 30 and 55 centimeters in length and the non-parallel sides (or legs) are 15 and 20 centimeters.
What are the areas of a trapezoid?
Area of a trapezoid formula. 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.
