Question

A sheet of paper 20cm× 16cm has a painting at the centre with a border of 2cm on all four sides . Find the area covered by the painting

Answer 1

Answer:192sq cm

Step-by-step explanation:Sheet of paper 20cm*16cm

In this paper we leave 2cm as boarder for painting on all 4sides

So now

painting length=20-2-2=14cm

breadth=16-2-2=12cm

Area=l×b=14×12=192sq.cm

Answer 2

The area covered by the painting is 192 $cm^{2}$.

Step-by-step explanation:

Given:

                            Length of the paper = 20 cm

                             Breadth of the paper = 16 cm

                             Border = 2 cm

                            Length of the painting = 20 - 4 = 16 cm

                            Breadth of the painting = 16 - 4 = 12 cm

We know that

                                      ⇒ Area = length x breadth

                                ⇒ Area of painting = (length x breadth) of painting

                                ⇒ Area of painting = 16 x 12

                                ⇒ Area of painting = 192 $cm^{2}$
