Answer:

$14 units$

Step-by-step explanation:

$Solution:-$

$A(5,1)B(7,1)$

$\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2} }$

$AB=\sqrt{(7-5)^{2} +(1-1)^{2} }$

$= \sqrt{2^{2} } =2$

$BC=\sqrt{7-7^{2}+(6-1)^{2} }$

$=\sqrt{5^{2} } =5$

$perimeter=2(AB)+2(BC)$

$= 2(2)+2(5)\\$

$= 4+10= 14$

A piece of rope can be cut into an exact number of 6 m lengths.

Gnesinka [82]

Answer:

24 m

Step-by-step explanation:

the smallest common multiple of 6 and 8.

I know already what that is (24) based on experience, but let's do this formally via prime factoring :

6 ÷ 2 = 3

3 ÷ 2 no

3 ÷ 3 = 1 finished

8 ÷ 2 = 4

4 ÷ 2 = 2

2 ÷ 2 = 1 finished

6 = 2 × 3

8 = 2 × 2 × 2

the smallest common multiple is the combination of the longest streaks per prime factor.

and that is 3 times a 2 and 1 time a 3 :

2 × 2 × 2 × 3 = 24 m
