Answer:
Yes, pythagorean theorem would help. Perimeter = 68 cm
Step-by-step explanation:
The formula for the area of Rhombus is A= (d1•d2)/2
Substitute the area and the length of one diagonal
240= (30•d2)/2
d2=16
Rhombus' diagonals bisect each other.
From one of the right triangles formed the legs would be 15 cm and 8 cm, use pythagorean theorem
15²+8² = x²
x=17
P= x•4
P= 68 cm
