Because it is a square table, that means all the sides are even. And to find the area, we do Height * Base. But again, because they're even, we would just need to find 2 numbers that multiply to be 400. And that number, is 20. 20 * 20 = 400. So the length of one side is 20.

Are these fractions equivalent or nonequivalent?<br> 4x/7y 8x/14y

ivann1987 [24]

Answer:

$\frac{8x}{14y} = \frac{ \frac{8x}{2} }{ \frac{14y}{2} } = \frac{4x}{7y} \\$

Hence, they are equivalent.
