Neon: Please do NOT encourage guessing here. Students need to learn how to solve problems and to specify their answers. Christine: Let the rectangle be L units long and W units wide. Write the formula for the perimeter, P, of this rectangle, using L and W as its dimensions.
|dw:1452825874980:dw|
Now, write a formula for the length, L, as a function of the width, W. You'll now have a formula for P and a formula for L. Use this set of equations to determine the width, W. Then find L from your formula.
How are you doing, Christine? Welcome to OpenStudy!
