Question

13. The length of a rectangle is 2 cm more than its breadth
and its perimeter is 28 cm. Find the length and breadth
of the rectangle.​

Answer 1

Answer:

ANSWER

Let breadth of the rectangle be 'b' cm.

So length of the rectangle will be 'b+2' cm.

Now

Perimeter =48

2(l+b)=48

2(b+2+b)=48

2b+2=24

2b=22

b=11 cm

l=b+2=13 cm

Then,

Area of the rectangle =lb

=13×11

=143 cm
