Answer:

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(3 $\sqrt{15}$ ) + 2( $\sqrt{15}$ ) ← distribute both parenthesis )

= 6 $\sqrt{15}$ + 2 $\sqrt{15}$

= 8 $\sqrt{15}$

What is 18 divided by 2/3?

pishuonlain [190]

Division is basically
x divided by y=x/y so
18 divided by 2/3= $\frac{18}{ \frac{2}{3} }$
we want the bottom number to be =1 so we multiply 2/3 by 3/2 to make it 1 (or 6/6=1), but we have to multiply the top number by 3/2 also so that we don't change the fraction and make our work useless so

$\frac{18}{ \frac{2}{3} } times \frac{ \frac{3}{2} }{ \frac{3}{2} } = \frac{ \frac{54}{2} }{ \frac{6}{6} }= \frac{27}{1}=27$
