Answer:
7.5 meters
Step-by-step explanation:
As with many quadrilaterals, pairs of sides have the same length, so the perimeter is twice the sum of two of the sides.
In a kite, generally, opposite sides have different lengths, so the perimeter is twice the sum of the lengths of opposite sides. That is
51 m = 2(18m + side opposite)
15 m = 2 × (side opposite)
7.5 m = side opposite
_____
<em>Comment on side lengths</em>
In a rectangle or parallelogram, the perimeter is twice the sum of adjacent sides. A kite is different in that adjacent sides may be the same length. If the kite is not a rhombus, <em>opposite</em> sides are <em>always</em> different lengths.

Answer:
48
Step-by-step explanation:
Ratio: Blue:yellow=4:3

4x12=48
So basically, You make a "equation".
You add 4 and 3 which is 7.
So since you know there is 84 total cards. That will equal the "?". So you divide the 84 and 7 since that will show what you will multiply with 4 and 3 to keep the blue and cards equally balanced. So you multiply the 12 and 4. Which is 48.
So there are 48 blue cards. Hope this helped you C:
