Q. The formula for the perimeter of a rectangle is P=2l+2w. Solve the formula for w in terms of P and l.Answer: w=
Subtract 2l from both sides: The formula for the perimeter of a rectangle is given by P=2l+2w. To solve for w, we need to isolate w on one side of the equation.
Divide both sides by 2: First, we subtract 2l from both sides of the equation to get 2w on one side by itself. This gives us P−2l=2w.
Final formula for w: Next, we divide both sides of the equation by 2 to solve for w. This gives us 2P−2l=w.
Final formula for w: Next, we divide both sides of the equation by 2 to solve for w. This gives us (P−2l)/2=w.Now we have the formula for w in terms of P and l, which is w=(P−2l)/2.
