Answer to Problem 10PSB
The area of trapezoid PQRS is
Explanation of Solution
Given:
The area of triangle PQS is
The median of trapezoid PQRS is
Base
Formula used:
Here, the formula is
Area of trapezoid =
(Where, “ a ” is upper base, “ b ”is lower base and “ h” is height)
Calculation: Here, area of trapezoid =
(Where, “ a ” is upper base, “ b ” is lower base and “ h ”is height)
Area =
→
Conclusion: Hence, the area of trapezoid PQRS is
