find the area of polygon?

rhombus with diagonals of 18 and 26

diagonals meet at right angle

base of 1/4 area = 13
altitude = 9
so total area = 4 (1/2)(9)(13)

find the area of polygon?

rhombus with diagonals of 22 and 34

What is the square with apothem of 9

To find the area of a rhombus with diagonals of 18 and 26, you can use the formula:

Area = (diagonal1 * diagonal2) / 2

In this case, diagonal1 is 18 and diagonal2 is 26. Plugging in these values, we get:

Area = (18 * 26) / 2

Area = 468 / 2

Area = 234 square units

Therefore, the area of the rhombus is 234 square units.
