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
