Top

An Isosceles trapezoid is a quadrilateral that has atleast a pair of parallel sides and other pair having no parallel sides but has equal length. It is given as

To find the area it uses the formula
Area = $\frac{b_1 + b_2}{2}$ $\times$ hWhere b1 and b2 are bases and h is the height.

Isosceles Trapezoid Calculator is an online tool to calculate area of isosceles trapezoid. If height, long base and short base are given then it can easily calculate the area of isosceles trapezoid.Please enter the values of height (h), long Base (b1) and short Base (b2) of the isosceles trapezoid and click solve to calculate the area of the trapezoid.
 

Steps for Area of Isosceles Trapezoid

Step 1 :  

Read the given problem and note down the value of height h, base b1 and and base b2.



Step 2 :  

To find the area of isoceles trapezoid use the formula


Area = $\frac{b_1 + b_2}{2}$ $\times$ h
Where b1 and b2 are bases and h is the height.


Subvstitute the value in above formula and get the answer.



Example problems on Area of Isosceles Trapezoid

  1. Calculate the area of the isoceles trapezoid if base lengths b1 is 5 cm b2 is 7 cm and height h is 10 cm.


    Step 1 :  

    Given: base length b1 = 5 cm, b2 = 7 cm and height h = 10 cm 



    Step 2 :  

    To find the area use formula


    Area of isoceles trapezoid = $\frac{b_1 + b_2}{2}$ $\times$ h




                                         = $\frac{5 + 7}{2}$ $\times$ 10




                                         = 60 cm2.



    Answer  :  

    Area of isoceles trapezoid= 60 cm2.



  2. What is the area of isoceles trapezoid of the base lengths are 6 cm and 10 cm whereas height is 8 cm?


    Step 1 :  

    Given: base length b1 = 6 cm, b2 = 10 cm and height h = 8 cm 



    Step 2 :  

    To find the area use formula


    Area of isoceles trapezoid = $\frac{b_1 + b_2}{2}$ $\times$ h




                                         = $\frac{6 + 10}{2}$ $\times$ 8




                                         = 64 cm2.



    Answer  :  

    Area of isoceles trapezoid = 64 cm2.
