From the diagram above, find the area of the triangle PQR
Attached Figure / Diagram
A
143cm\(^2\)
B
120cm\(^2\)
C
130cm\(^2\)
D
117cm\(^2\)
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Area of triangle PQR = \(\frac{1}{2}\) x QR x Pc
Where QR = base of triangle PQR, Pc = height of triangle PQR
Area of triangle PQR = \(\frac{1}{2}\) x 20 x 13 = 10 x 13 = 130cm\(^2\).
