Question

The length, breadth, and height of a box are 75cm, 85cm, and 95cm respectively. Find the longest tape which can measure the three dimensions of the room exactly. *

Answer 1

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
