plz tell the process of doing this question​

Answer 1

Answer:

perimeter= 130

also, perimeter=2(length+breadth)

130=2(length+30)

65=length+30

thus length= 35

now, area= length* breadth

=30*35

=1050

Answer 2

Answer:

length=35cm... Area = 1050 cm2

Step-by-step explanation:

given, breadth=30cm and Perimeter=130cm

Perimeter of a rectangle=2(l+b)

130=2(l+30)

130=2l + 60

130-60 = 2l

70=2l

Therefore, l=35cm

So length is 35cm

Now, Area= l * b

= 35*30

= 1050 cm2
