Question

1

The formula for the area of a regular polygon is A = 1/2ap. What is the equation solved for a?
O a= 2A
O a= 2A-p
O a=2p/A
O a=2A/p

Answer 1

a =
`(2A)/(p)`

Explanation:

Given

A =
`(1)/(2)` ap ( multiply both sides by 2 to clear the fraction )

2A = ap ( isolate a by dividing both sides by p )

`(2A)/(p)` = a
