Answer 1

Hi Friend !!!

Here is ur answer !!!

Hope it helps u :-)

Answer 2

$\huge\bold{Solution}$

$<b><i>$ Given:-

Diagonal of Rhombus are 15cm, 36cm

This diagonal will divide into two equal parts

15 / 2 = 7.5cm

36/ 2 = 18cm

As we diagonal intersect at 90 degree

then,

we use Pythagoras theorem

H² = p² + b²

x² = (7.5)² + ( 18)²

x² = 380

x= √380

X, = 19.5 approx!

So the next step is of perimeter

perimeter of rhombus = 4* side

4* 19.5
= 78cm

$\huge\boxed{ perimeter = 78cm}$
