X=7.5 area= 42
You know that the total perimeter is 39 so to find x you need to add what you already have. You’ll find there are 3 sides you don’t know the length of and all you have to do is find the shorter one which is basically 9-7=2 then add everything together and subtract it from 39 then divide it by 2 to find the two sides left

Anyone here who can help me with this?
Mandarinka [93]

Answer:

D. 16 years old

Step-by-step explanation:

<u>Step 1:</u> Let T be Tien's age and J as Jordan's age (today),

T=\frac{1}{4}J

<u>Step 2:</u> Let T be Tien's age and J as Jordan's age (in 2 years),

T+2=\frac{1}{3} (J+2)

T=\frac{1}{3}(J+2)-2

<u>Step 3:</u> As their age differences will always be similar we can have the two equations above equal to find Jordan's age,

\frac{1}{4} J=\frac{1}{3}(J+2)-2\\\frac{1}{4}J-\frac{1}{3}J=\frac{2}{3}  -2 \\-\frac{1}{12}J= -\frac{4}{3} \\\\J=16
