Question

find the breath and perimeter of the rectangle if it's area is 96 centimetre square and length is 12​

Answer 1

Answer:

breadth=8

Step-by-step explanation:

and perimeter=40

Answer 2

Step-by-step explanation:

Given,

Length= 12cm ; Area=96cm²

Let us find the breadth by using the given area,

Formula of area of rectangle = Length× Breadth

By the substituting the given values,

                                       Area=l×b

                                         96= 12×b

 Now taking 12 on left hand side it becomes division,

                                            $\frac{96}{12}$ = b

                                              b=8cm

  after cancellation or after division we get breadth as 8cm.

         Now we may find the perimeter.

               formula, Perimeter of rectangle=2(l + b)

                                                               P=2(12 + 8)

                                                               P= 2(20) / 2 ×20

                                                               P= 40cm.

So the breadth is 8cm and the perimeter is 40cm.
