Answer to Problem 10PSB

The length of PQ is 10

Explanation of Solution

Given:

The area of triangle PQS is 25

The median of trapezoid PQRS is 14 and

Base RS¯ measures 18

Concept used:

Here, we are using the formula

Median = 12(lowerbase+upperbase)

Calculation: Here, Median = 12(lowerbase+upperbase)

  14=12(18+PQ)

  28=18+PQ

  PQ=10

Conclusion: Hence, the length of PQ is 10

b.

To determine

To calculate:The height to base PQ¯ of ΔPQS

Answer to Problem 10PSB

The height to base PQ¯ of ΔPQS is 5

Explanation of Solution

Given:

The area of triangle PQS is 25

The median of trapezoid PQRS is 14 and

Base RS¯ measures 18

Formula used:

Here, the formula is

Area of triangle = 12×base×height

Calculation:

Here,

Area = 12×base×height

  25=12×10×height

  height=5

Conclusion: Hence, the height to base PQ¯ of ΔPQS is 5

Answer to Problem 10PSB

The height of trapezoid PQRS is 5

Explanation of Solution

Given:

The area of triangle PQS is 25

The median of trapezoid PQRS is 14 and

Base RS¯ measures 18

Calculation:

Here, the height of ΔPQS = height of trapezoid PQRS

Conclusion: Hence, the height of trapezoid PQRS is 5

Answer to Problem 10PSB

The area of trapezoid PQRS is 70

Explanation of Solution

Given:

The area of triangle PQS is 25

The median of trapezoid PQRS is 14 and

Base RS¯ measures 18

Formula used:

Here, the formula is

Area of trapezoid = 12(a+b)×h

(Where, “ a ” is upper base, “ b ”is lower base and “ h” is height)

Calculation: Here, area of trapezoid = 12(a+b)×h

(Where, “ a ” is upper base, “ b ” is lower base and “ h ”is height)

Area = 12(10+18)×5

70

Conclusion: Hence, the area of trapezoid PQRS is 70
