Answer 2

p=47cm

so,

in peremeter there are 2 lengths and 2 breadths

and it's 1 length is 15 so another will also be 15 ,

so,let breadth =x

so 2 breadth = 2x

15+15+2x=47cm

30 +2x=47cm

2x=47-30

x=17/2

x=8.5cm

now we have breadth and lengths

now

formula of area of rectangle=l*b

now 8.5*15=127.5 cm square

so area of rectangle is 127.5 cm square
