because dimensions generally mean length and breadth........

anonymous · Answer

I can give you one. (:
the area of the rectangle is 180 square cm. Find its dimensions. Use the equation: L(L+3) = 180

anonymous · Answer

Could you please explain how you get the answer step by step?

anonymous · Answer

L here i guess stands for length.....

anonymous · Answer

L(L+3)=180
$$L ^{2}+3L-180=0$$
