Explanation:

A=s^2

A=15^2=225 ft^2

15-10=5

5*5=25

25/2=12.5

225-12.5=212.5

Answer 2

Answer: 212.5 square feet

Explanation:

If we were to complete the square, the total area of the square would be
`15^2=225` square feet.

The area of the triangle added to 'complete the square' is
`(1)/(2)(15-10)(15-10)=12.5` square feet.

So, the area of the floor is
`225-12.5=212.5` square feet.
