Answer:
, 
, 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Find the value of the constant of proportionality k
take any ordered pair from the data
For x=25, y=160

substitute the values of x and y

simplify

The linear equation is equal to

S = 1/2 h * (a+b)
SA = sqroot of (4^2 + 1^2) =sqrt17
MK = sqrt of (11^2 + 3^2) = sqrt130
ST = sqrt of (4^2 + 1^2) = sqrt17
S = 1/2 * sqrt17 (sqrt17+sqrt30)=32 unit square
