Answer:
It's 31.5
Step-by-step explanation: The formula for right triangle is A=ab/2. A=area, a is one of the legs and b is the other leg. So you had for one leg 9 and for the other 7. You multiple 9 x 7 = 63. 63/2 = 31.5 for the area
L, A, B = the amount of money each person has.
L + A + B = 70
B = 3L
L = A +5 or A = L-5
Set up an equation in L only:
L + L - 5 +3L =70
5L -5 = 70
5L =75
L = 15
follows
B=3*15 =45
A = 15 - 5 = 10
