Plz asap
the sides of a quadrilateral are 3, 4, 5, and 6.
find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.
i've done everything possible and still keep getting wrong plz

When a shape's area is 9 times as great, the one dimension difference is √9=3 times as great. Therefore the length of all sides are 3 times of the corresponding sides of the original shape. The shortest side in the original shape is 3, the larger one is 3 times of that, which is 9. General rule, if a similar shape is x times ratio in terms of sides, the area will be x^2 times the original.  Hope it helps.
