R=pl\A.make p the subject of the formular and A the subject of the formular.
I'll assume you meant
R = pl/A
p=AR/l
A=pl/R
l=AR/p
and that's "formula" with no "r" ...
To make p the subject of the formula R=pl/A, we need to isolate p on one side of the equation. Here's how you can do it step by step:
1. Start with the formula: R = pl/A
2. Multiply both sides of the equation by A to get rid of the denominator: AR = pl
3. Divide both sides of the equation by l: (AR)/l = p
So, p = (AR)/l.
To make A the subject of the formula, we need to isolate A on one side of the equation. Here's how you can do it step by step:
1. Start with the formula: R = pl/A
2. Multiply both sides of the equation by A to get rid of the denominator: AR = pl
3. Divide both sides of the equation by R: AR/R = pl/R
4. Simplify the left side of the equation: A = pl/R
So, A = pl/R.
Remember, when making a variable the subject of a formula, the goal is to isolate that variable on one side of the equation by performing necessary operations.
