Step-by-step explanation:
Area of triangle formula: 1/2 x base x height

Kelby drank 168 glasses of water per week
i.e 24 glasses per day
Since 8 eight-ounce glass of water is for every 50 pounds.
1 eight-ounce glass is for = 50/8 pounds
and 24 glasses of water is for = 50*24/8
= 150pounds
So kelby probably weighs 150 pounds
