WHAT THE SURFACE AREA​

Mathematics
1 answer:
levacccp [35]3 years ago
7 0

Hey there! :)

Answer:

16 m².

Step-by-step explanation:

Find the surface area by finding the areas of each face:

The base is a square, so use the formula A = s²

A = 2²

A = 4 m².

Find the areas of the congruent triangular lateral sides. Use the formula:

A = 1/2 (bh)

A = 1/2 (2 · 3)

A = 1/2 (6)

A = 3 m².

There are 4 triangular faces, therefore:

3 × 4 = 12 m².

Add up the areas from the triangles and square base:

12 + 4 = 16 m².

Therefore, the surface area of this square pyramid is 16 m².

Number 28 ignore the bubbled in answer
Ghella [55]

Answer:

y = -7x+34

Step-by-step explanation:

We have 2 points, so we can find the slope

m = (y2-y1)/(x2-x1)

    = (6--1)/(4-5)

    = (6+1)/(4-5)

     = 7/-1

    = -7

We can use point slope form to make an equation

y-y1 = m(x-x1)

y--1 = -7(x-5)

y+1 = -7(x-5)

Distribute

y+1 = -7x+35

Subtract 1 from each side

y+1-1 = -7x+35-1

y = -7x+34
