What is the surface area of the right prism given below?

For this case, we have that the area of the surface of the figure shown is given by:

: The area of the upper rectangle (inclined)

: The area of the two triangles.

: The area of the base of the prism

: The area of the rear rectangle

We apply Pythagoras to know the length of the inclined side of the rectangle:

Thus, the is given by:

We look for the area given by the triangles, knowing that the area of a triangle is , then:

We look for the area of the base of the prism:

We look for the area of the posterior rectangle:

Adding we have:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
