By what factor does the area change if one diagonal is doubled? explain.

The area of deltoid is defined by formula:

Where e and f are diagonals.

If you were to double the size of either one. Let's say f. You would result with:

Which means if either of diagonals double in length the area of deltoid will be twice as big as it was before.

Hope this helps.

the kite, which looks more like a rhombus but being called a kite, will look like the one in the picture below.

now, as you see in the picture, the kite is really 4 congruent triangles, each with a base of 2.5 and a height of 5, so their area is

i believe your answer is a
