​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

12 sq cm

Step-by-step explanation:

Perimeter of Rhombus= 4a

side = 20/4 = 5

Area= (d1 x d2)/2

d1 = 6cm

d2 =  x

3 sq + x square = 5 sq

9 + x sq = 25

25 - 9 = 16

x sq = 16

x = sq root of 16

x = 4

diagonal 2 = 4 * 2

= 8 cm

Area = (d1 * d2) /2

= (4*6)/2

=24/2 = 12 sq  cm
