Answer 1

I dont know the ans.........

Answer 2

Given :-

Length of rectangle =8 cm

Which means :-

The breadth of this rectangle :-

$= \frac{1}{2} \: \: \: of \: \: \: 8$

$= \frac{1}{2} \times8$

$= \frac{1 \times 8}{2}$

$= \frac{8}{2}$

$= \bold{4 \: cm}$

Thus, the breadth of this rectangle =4 cm

Then, the perimeter of this rectangle :-

$= 2(l + b)$

$= 2(8 + 4)$

$= 2(12)$

$= \bold{24 \: cm}$

Therefore, the perimeter of this rectangle =24 cm
