- Length be x
- Breadth be y
--(1)
And
- xy=45
--(2)
Adding (1) and (2)
- 2x=18
- x=9
And
- 9+y=14=>y=5

y squared equals x squared minus z squared.
Solution:
The given triangle is a right angled triangle.
Hypotenuse = x, Base = y, Height = z
Using Pythagoras theorem, we can find the lengths of the sides of the right triangle.
Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
Subtract from both sides of the equation.
Switch the sides
y squared equals x squared minus z squared.
Hence Option B is the correct answer.
