Answer:
The answer is 7
Step-by-step explanation:
Because 840 divided by 120 is 7
50
I just think it's 50 because I was on this problem for a long time and I just took my best guess
M is mid point of CP. M will divide the BPC in two equal parts BMC and BMP.
Area of BMP is equal to 21m^2
Since, BMC = BMP
Area of BPC = Area of BMC +Area of BMP = 21 + 21 = 42m^2
and since ratio of AP:BP =1:3 so the area of BMP will be 1/3 of Area of ABC
hence, Area of ABC = 63m^2
