The triangle is a right triangle, 9, 12 & 15.
The triangle's area = b*h/2 = 9*12/2 = 54 sq meters each end.
------------
The 3 rectangles are 10 by 9, 12 & 15
Area of the 3 = 10*(9 + 12 + 15) = 360 sq meters
-----
Total area = 360 + 2*54
= 468 sq meters
y = 55/10x + 50 is the equation to represent this situation
The diameter of human hair is 8.0 x 10^-6
hope this helps :)
