Question

Q4. The length and breadth of rectangular room are 8 2/3(mixed fraction)and 6 4/2m(mixed fraction)find the perimeter of room.​

Answer 1

Answer:

36m

Step-by-step explanation:

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters

Answer 2

Answer:

Given :-

Length (l) = $8\frac{2}{3}m \: = \: \frac{26}{3}m$

Breadth (b) = $6\frac{4}{2} m \: = \: \frac{16}{2} m$

Formula :-

$\green{p \: = \: 2(l+b)$

Solution :-

$p \: = \: 2(\frac{26}{3} + \frac{16}{2})\\ \\LCM \: of \: 3 , 2 = 6\\\\ p = 2( \frac{52 + 48}{6} )\\\\p=2(\frac{100}{6})\\\\p=2(\frac{50}{3})\\\\p=\frac{100}{3} \\\\\red{p=33.33m}$

Hope it helps you !!
