Question

The length of rightangular is two times it's breadth.If the perimeter of the right angular is 36cm.find it's areas

Answer 1

Answer:

Hey there!

Step-by-step explanation:

Let the breadth be x cm.

Then, length=2x cm

Perimeter of rectangle=2(l+b)=2(x+2x)=2x+4x=6x

But A/Q,

6x=36cm

x=36/6=6cm(this is breadth)

So, length=2×6=12cm

Area=l×b=12×6=72cm
