Question on: WAEC Mathematics - 2008
If the perimeter of (\bigtriangleup)PQR in thr diagram is 24cm, what is the area of (\bigtriangleup)PRS?
A
19.5cm2
B
15.0cm2
C
13.0cm2
D
9.3cm2
Ask EduPadi AI for a detailed answer
Correct Option: B
Perimeter of (\bigtriangleup) PQR = PQ + QR + PR
24cm = 6cm + 8cm = PR
24 = 14 + PR
PR = 24 - 14 = 10cm
Area of (\bigtriangleup) PRS = (\frac{1}{2} \times 10 \times 3cm^3)
= 15cm3
