Question

The distance from the house to the mall is ?

  1. 15
  2. 16
  3. 18
  4. 17

hintHint:

As looking at figure we get that it is a right angled triangle. So, by using Pythagoras theorem we can find the distance between mall and house and Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. 

The correct answer is: 17


    APQ,
    h squared equals p squared plus b squared
h squared equals 15 squared plus 8 squared
h squared equals 225 plus 64
space space space space equals 289
h equals space 17 space
    So, the distance between house and mall is 17 miles.
