Answer:

1. x²=a² + b²

x²=10²+7²

x²=100+49

x²=149

x=√149

12.206555615

x=12.2

2.x²= a²+b²

x²=19²+ 21²

x²=361+441

x²=802

x=√802

x=28.319604517

x=28.3

3.x²=a²+b²

x²=27²+16²

x²=729+256

x²=985

x=√985

x=31.384709652

x=31.3

4.x²=a²+b²

x²= 163.84+ 28.109

x²=191.93

x=√191.93

x=13.853880322

the area of a bathroom floor measures 3 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square yards.

wel

Using the area, the number of tiles needed to cover the floor is 6.

The area is the region bounded by the shape of an object.

Therefore, the bathroom floor measures 3 yards by 3yards.

Hence the area of the bathroom floor can be calculated as follows;

area of the bathroom floor = 3 × 3

area of the bathroom floor = 9 yards²

The area of the custom tiles that makes the flooring is 1 1 /2 square yards.

Hence,

number of tiles needed to cover the floor = 9 ÷ 3 /2

number of tiles needed to cover the floor = 9 × 2 / 3

number of tiles needed to cover the floor = 18 / 3

number of tiles needed to cover the floor = 6
