What is the perimeter of triangle ABC ? 11 units 14 units 16 units 20 units Coordinate graph showing triangle A B C. Triangle A

professor190 [17]

Answer:

The perimeter is equal to $16\ units$

Step-by-step explanation:

we have that

$A(-1,1),B(2,5),C(5,1)$

The perimeter of triangle ABC is equal to

$P=AB+BC+AC$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance AB

$A(-1,1),B(2,5)$

$AB=\sqrt{(5-1)^{2}+(2+1)^{2}}$

$AB=\sqrt{(4)^{2}+(3)^{2}}$

$AB=\sqrt{25}$

$AB=5\ units$

step 2

Find the distance BC

$B(2,5),C(5,1)$

$BC=\sqrt{(1-5)^{2}+(5-2)^{2}}$

$BC=\sqrt{(-4)^{2}+(3)^{2}}$

$BC=\sqrt{25}$

$BC=5\ units$

step 3

Find the distance AC

$A(-1,1),C(5,1)$

$AC=\sqrt{(1-1)^{2}+(5+1)^{2}}$

$AC=\sqrt{(0)^{2}+(6)^{2}}$

$AC=\sqrt{36}$

$AC=6\ units$

step 4

Find the perimeter

$P=5+5+6=16\ units$

Sveta_85 [38]

Answer:

16 students can sit around a cluster of 7 square table.

Step-by-step explanation:

Consider the provided information.

We need to find how many students can sit around a cluster of 7 square table.

The tables in a classroom have square tops.

Four students can comfortably sit at each table with ample working space.

If we put the tables together in cluster it will look as shown in figure.

From the pattern we can observe that:

Number of square table in each cluster Total number of students

1 4

2 6

3 8

4 10

5 12

6 14

7 16

Hence, 16 students can sit around a cluster of 7 square table.

Whats the length of the patio?

nikdorinn [45]

Answer:

Length = 20 feet; x = 14

Step-by-step explanation:

Parameter = width + length + width + length

64 feet = 12 feet × 2 + (x + 6) feet × 2

64 = 24 + (x + 6) × 2

64 - 24 = (x + 6) × 2

40 = (x + 6) × 2

40 ÷ 2 = x + 6

20 = x + 6

20 = length

20 - 6 = x

14 = x
