Question

The length of a rectangle is twice the width. The area is 162yd^2. Find the length and the width.
The length is_____yd
The width is_____yd

lgbasallote · Answer

l = 2w

area = l x w = 162

so 

$$2w \times w = 162$$ $$2w^2 = 162$$ divide by 2 $$w^2 = 81$$ can you do it from there?
