Answer:

Step-by-step explanation:

if the breadth is 5cm, then you divide 30/5 to get your length since it's length times breadth to get the area, so 6cm for the length

and then it's 2b plus 2l to get your perimeter so

2(5)+2(6)=p

10 plus 12 equals p

22 is your perimeter, 6 is your length

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ = $a^{\frac{1}{2} }$

Thus

( $\sqrt{a}$ )² = $a^{\frac{1}{2} }$ × $a^{\frac{1}{2} }$ = $a^{(\frac{1}{2}+\frac{1}{2}) }$ = $a^{1}$ = a → B
