a monument at a park is in the shape of a right square pyramid. a diagram of the pyramid and its net are shown.

what is the surface area of the monument?

enter the answer in the box.

m²

The surface area of the monument = 56 m^2

Step-by-step explanation:

A monument which is in the shape of square pyramid and the net is given.

The surface is nothing but the sum of areas of all the faces.

There are 4 congruent triangles on the sides and 1 square base.

Let's find the area of the base.

Area of the base = side *side

Here side = 4 m

Area of the base = 4*4 = 16 m^2

Now let's find the area of 1 triangle.

The base of the triangle is 4 and the height is 5.

Area of the triangle = 1/2*base * height

= 1/2*4*5

= 2*5

= 10 m^2

Area of the 1 triangle = 10m^2

We know the 4 triangles are congruent to each other.

Surface area = base area + 4(area of the triangle)

= 16 + 4(10)

= 16 + 40

The surface area of the monument = 56 m^2

Actually, it's 14.

Step-by-step explanation:

I took the test online in K12 and when I reviewed it said that 14 is the correct answer.

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
