Answer 1

Answer: Area  = 120sq cm

Step-by-step explanation:

perimeter=4s

52=4s

s=52/4=13cm. 

as diagonal divides rhombus into 2 triangles, we will use Heron's formula

√s(s-a)(s-b)(s-c)

s=(a+b+c)/2

a= side 1 ,b=side 2, c=side 3

s=(13+13+24)/2

 =50/2

 =25

√s(s-a)(s-b)(s-c)

√25(25-24)(25-13)(25-13)

=√25*1*12*12

=√5²*12²

=5*12

=60

as 2 triangles are formed,

area of rhombus= 2*60

                         =120 sq. cm
