How do I find the area of this figure?

Answer:
24cm^2
Step-by-step explanation:
area of rhombus/parallelogram = 1/2 x diagonal 1 x diagonal 2
to find the value of diagonal 2, we use Pythagoras Theorem.
so 100 - 36 = 64. square root of 64 = 8. Thus, second diagonal = 8
Now find area: 1/2 x 8 x 6 = 24cm ^2
