The surface area of a swimming pool is 373 square feet. What is it’s surface area in square meters?

jeka57 [31]

The surface area of swimming pool is 373 square feet .

In this question, we have to convert square feet to square meters, that is

$1 feet = 0.3048 meter$

Squaring both sides ,

$1 feet^2 = 0.3048^2 meter^2$

$1 feet ^2 = 0.09290304 meter^2$

And

$373 feet^2 = 373* 0.09290304 meter^2$

$373 feet^2= 34.653meter^2$
