Let Adam's age be
, since the father is 3 times as old as him , then the father will be
.

Answer:
Area = 166cm² (Approximately)
Step-by-step explanation:
To solve this, let's recall the formula for the area of a REGULAR Hexagon.
The area of a REGULAR Hexagon is expressed as:
A = (3√3 * a²) / 2
Where a is the length of one side of the Hexagon.
a= 8cm.
Area = (3√3 * 8²) / 2
Area = (3√3 * 64) / 2
Area = (192√3) / 2
Area = 332.55 / 2
Area = 166.28cm²
Area = 166cm² (Approximately)
The answer would be 6ft and the reason why is because the shed
