Question

A room floor is 192 square meter in area if its length is 16m what's its perimeter

Answer 1

$\huge\bold{\gray{\sf{Answer:}}}$

$\bold{Explanation:}$

Given:

Area of room floor is 192 sq.metre

Length of room floor =16m

To Find :

Perimeter

=>The room floor is in the shape of a rectangle so,the area of rectangle will be the area of room floor and the perimeter of the rectangle will be it's perimeter also.

Area of room floor =$length \times breadth$

$= > 16 \times breadth = 192$

$= > b = \frac{192}{16} = 12$

$\therefore$ Breadth is 12 m

Now, we have to find its perimeter

Perimeter of the floor of room =$2(l + b)$

$= 2(16 + 12) = 2(28) = 56m$

$\therefore$ Perimeter of room floor is 56m.
