3 sie 2023 · The area of a trapezoid is the total space enclosed by it. Since a trapezoid is a two-dimensional shape, its area also lies in a two-dimensional plane. The unit of area is in square units such as m 2, cm 2, in 2, or ft 2. Formula Using Height and Base Lengths. The basic formula to calculate the area of a trapezoid is given below:
Area of Trapezoids – Example 1: Calculate the area of the trapezoid. Solution: Use trapezoid area formula: \ (A= \frac {1} {2} h (b_ {1}+b_ {2 }) \) \ (b_ {1}=14 cm , b_ {2}=18\) \ (cm\) and \ (h=20\) \ (cm\) Then: \ (A= \frac {1} {2} (20) (14+18)=10 (32)=320\) \ (cm^2\) The Best Book to Help You Ace Pre-Algebra.
The area of a trapezoid formula is: A = (1/2) × (a + b) × h. Here, the components of the formula of the area of the trapezoid are: ‘a’ and ‘b’ are the lengths of the two parallel bases of the trapezoid. ‘h’ is the height among the parallel bases of the trapezoid.
Find the missing base or height by substituting the known values in the rearranged area of the trapezoid formula. Reiterate the concept of finding areas with this bundle of printable worksheets for grade 7 and grade 8.
Directions: Find the area of each trapezoid. The formula to calculate the area of a trapezoid is. Area = ½ (base 1 + base 2) x height. Write your answer in the space provided.
