Question

don't do no. 6 just answer no. 5 fast step by step​

Answer 1

hey there!

Area of a rectangle = length *breadth

$72\frac{5}{6} = 12\frac{2}{3} * breadth\\\\\frac{437}{6} = \frac{38}{3} * breadth \\\\\frac{437}{6} * \frac{3}{38} = breadth \\\\\frac{23}{4} = breadth$

_____________________________________________

Now,

$perimeter = 2(l +b )\\ = 2( \frac{38}{3} + \frac{23}{4} )\\\\ = 2 ( \frac{114+69}{12} )\\\\ = 2(\frac{183}{12} )\\\\ = \frac{183}{6} or 30\frac{3}{6}$
