Answer 1

Answer:

length=15cm

Area=225 sq. cm

Step-by-step explanation:

Perimeter of rectangle=60cm

2(l+b)=60

(l+b)=60/2

l+b=30

l+15=30

l=30-15

l=15cm

Length of rectangle=15cm

Area of rectangle=l*b

=15*15

=225 sq. cm

Area of rectangle=225 sq. cm

Hope it helps....

All the best!!!!!

Answer 2

Perimeter of rectangle=60cm

⇒2(l+b)=60

     (l+b)=$\frac{60}{2}$

      l+b=30

Given b = 15cm

⇒l+15=30

    l=30-15

    l=15cm

Length of rectangle =15cm

 Area of rectangle   =l*b

                                  =15*15

                                  =225 $cm^{2}$

Area of rectangle 225 $cm^{2}$
