Step-by-step explanation:
d1 = diagonal 1
d2 = diahonal 2
24cm²= d1*d2/2
24 = 6*d2/2
24*2=6*d2
48=6*d2
d2 = 48/6
= 8
d1=6cm=ac
d2=8cm=bd
diagonls of a rhombus are perpendicular
ao = oc = 6/2 = 3
bo = od = 8/2 = 4
AB=side of rhombus
AB²= bo²+ oc²
= 16 + 9
= 25
AB = square root of 25 = 5cm
perimeter of rhombus = 5*4= 20cm
