Chapter E, Problem 11.4EX

To determine

To find the area of the trapezium.

Answer to Problem 11.4EX

Option (c)

Explanation of Solution

Given information: The length of the parallel sides and height are 7, 8 and 6 respectively.

Concept used:

  $\text{Area}\text{of}\text{trapezium}=\frac{1}{2}\times (\text{sum}\text{of}\text{parallel}\text{sides})\times (\text{height})$

  $\text{Area}\text{of}\text{trapezium}=\frac{1}{2}\times (7+8)\times (6)=45$

  $\text{Circumference}=2\pi r=10\pi$

Hence, the area of the trapezium is 45 units .
