Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².
