Step 1) Find the area of the faces

There are 4 triangular faces on this rectangular pyramid. In this case, they are all the same, because each triangle has the same base and height. We will find the area of 1 triangle and multiply it by 4 to find the area of all of the triangular faces.

A = 1/2 x 3 x 2

A = 1/2 x 6

A = 3

3 x 4 = 12

A = 12 cm^2

Step 2) Find the area of the base

The base has a length of 2 cm and a width of 2 cm. We can find the area of the base by multiplying the length and width because the base is a rectangle.

A = 2 x 2

A = 4 cm^2

Step 3) Add the areas together

Now, we need to add the area of the faces and the area of the base together to find the surface area.

A = 12 + 4

A = 16 square centimeters

Hope this helps! :)

Answer:

OPTION A: 2x + 3y = 5

Step-by-step explanation:

The product of slopes of two perpendicular lines is -1.

We rewrite the given equation as follows:

2y = 3x + 2

⇒ y = $ \frac{3}{2}x + 1 $

The general equation of the line is: y = mx + c, where 'm' is the slope of the line.

Here, m = $ \frac{3}{2} $.

Therefore, the slope of the line perpendicular to the line given = $ \frac{-2}{3} $ because $ \frac{3}{2} \times \frac{-2}{3} = -1 $.

To determine the equation of the line passing through the given point and a slope we use the Slope - One - point formula which is:

                                  y - y₁ = m(x - x₁)

The point is: (x₁, y₁) = (-2, 3)

Therefore, the equation is:

y - 3 = $ \frac{-2}{3} $(x + 2) $

⇒ 3y - 9 = -2(x + 2)

⇒ 3y - 9 = -2x - 4

⇒ 2x + 3y = 5 is the required equation.
