Q7. The length and breadth of a rectangular room is 7*1/2

m and 5*1/6

m . Find the

perimeter of the room​

Answer 1

Answer:

perimeter of rectangular room= 152m

Step-by-step explanation:

the length of rectangular room = 7*1/2

= 15/2

breadth = 5*1/6

= 31/6

perimeter of rectangular room= 2(l+b)

= 2(15/2+31/6)

=2(45+31)

= 2×76

= 152m

Answer 2

25 whole 1/3

Step-by-step explanation:

Length= 7 whole 1/2

Breadth= 5 whole 1/6

Perimeter of rectangle= 2×(L+B)

$2 \times (7 \frac{1}{2} + 5 \frac{1}{6} )$

$\frac{2}{1} \times ( \frac{38}{3} )$

$= \frac{76}{3} \: \: ans \: = 25 \frac{1}{3}$
