Aperson who is 6.2 feet tall is standing in a pool. the top of the person's head is 2.8 feet above the surface of the water. how deep is the pool?

3.8 feet

Step-by-step explanation:

Given that the person is standing in a pool.  That means he is keeping his feet at the bottom level of the pool.  His height is 6.2 ft.  

Top of the person head above the surface of water= 2.8 feet.

Hence height of the person= Top of the person head above the surface of water+depth of the pool

6.2 = 2.8+depth of pool

Depth of pool = 6.2-2.8 = 3.4 feet.

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
