aren't you asking the length of and area of 48 yds with a width of 3 yds?

anonymous · Answer

yes...... sry I got confuesed

anonymous · Answer

that mean you know that the area of a rectangle is $$A=\frac{ 1 }{ 2}(l*b)$$
right?

anonymous · Answer

wait do I multiply 48 by 2 than add 3 or multiply that too?

anonymous · Answer

sorry...that was the area of a triangle....but of the rectangle is $$A=l*b$$

anonymous · Answer

that mean you need to solve for $$l$$ becacuse we $$b$$ is given and the area is given

anonymous · Answer

mind you $$b $$ is the same as width
