Question

The length of a rectangle is 2cm more than its breadth, and it's perimeter is 28cm. find the length and breadth of the rectangle.​

Answer 1

Answer:

8

Step-by-step explanation:

breadth = x

length = x+2

perimeter = 2*(length+breadth)

28 = 2*(x+x+2)

28 = 2* (2x+2)

2x+2 = 28/2 = 14

x = (14-2)/2=6

x+2 = 8

Answer 2

Step-by-step explanation:

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 cm2
