Answer:
73
Step-by-step explanation:
Original number: XY
x = 3y - 2
10y + x = (10x + y) / 2 + 1/2
substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2
* 2 both sides and simplify: 26y - 4 = 31y - 19
31y - 26y = -4 + 19
5y = 15
y = 3
x = 7
Original number: 73
Area of a Triangle= 1/2 (bh)
96=1/2(b x 8)
96/8=1/2b
12=1/2b
12 x 2/1=b
24=b
A=1/2(24(8))
P=24 x 3
P=72
Y= 1x is the correct answer
