Given :-

Length of floor = 19 m

Area of floor = 247 m

====================

To Find :-

Perimeter of floor

===================

Solution :-

We know that,

Area of rectangle = Length * Breadth

___________[Put Values]

→ 247 = 19 * Breadth

→ 247/19 = Breadth

→ Breadth = 13 m

=====================

Now,

Perimeter = 2(L + B)

→ 2(19 + 13)

→ 2(32)

→ 64

Hence, perimeter is 64 m
