Find the area of the triangle QRS
A) 90 cm
B) 80 cm
C) 110 cm
D) 55 cm
E) 45 cm
Solution
• For calculating the area of a triangle, we need to know the basic parameters viz., base and height, and when we substitute them using Area = ½* Base * Height, we will get the area.
• The base can be any side of a given triangle; it can be QR, RS and QS. Depending on the side we choose, the height will be the altitude drawn from the angle opposite to the base.
So PQ^2 = QR^2 + PR^2
• Let us take...
