Question

A ballroom has a square dance floor. The area of the floor is 400 square feet. If the length of each side of the square increased by one foot, would its area be a rational number? Choose each statement that is true about the new dance floor.

Answer 1

Area =S²+1

400-1=s²+1-1

√399=√s²

S=19.97

A=399 therefore area is a rational number

Step-by-step explanation: plus one since it is increased by one foot. Every whole number is a rational number because every whole number can be expressed as a fraction
