The lateral area is the area of everything but the base. A shortcut formula for this area is Ph. (where P is the perimeter of the base and h is the height of the prism).

So the lateral area is (3+9+9.49)x37 = 795.13 m^2 or 795 m^2

The surface area is the lateral area plus the area of the 2 bases. The base is a triangle. (area = 1/2 bh)

Since there are two identical bases, the total area of the base is just 3x9 = 27

So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.

Answer:

Option A - $-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x+\frac{5}{12}y-10$

Step-by-step explanation:

Given : Expression $-\frac{5}{6}(x-\frac{1}{2}y+12)$

To find : Which expression is equivalent to given expression ?

Solution :

Expression $-\frac{5}{6}(x-\frac{1}{2}y+12)$

Applying distributive property, $a(b+c)=ab+ac$

$-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x-(-\frac{5}{6})(\frac{1}{2}y)+(-\frac{5}{6})(12)$

$-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x+\frac{5}{12}y-10$

Therefore, option A is correct.
