Question

A picture is 1.2m long and 50 cm broad. What is the length of the wooden frame needed for framing the picture? what is the area of the glass required to cover the picture in the frame ​

Answer 1

Answer:

Step-by-step explanation:

Given ,

L=1.2m =1.2*100=120cm

B=50cm

There fore, perimeter=2(l +b)

=2(120+50)

=340cm

Area of glass= l×b

=120×50

=6000cm^2

Answer 2

Answer:

your answer

Step-by-step explanation:

consider the problem

Length of the wooden frame needed is equal to the how long the picture.

Therefore, Length of the picture =1.2m=120cm

And area of glass required to cover the picture is equal to area of the picture,

Hence Required Area=length×breath

=0.5×1.2=0.6m

Hence, the required area to cover the picture is 60cm.
