Question

a picture is 1.2 metre 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

Step-by-step explanation:

l=1.2m=120cm

b=50cm

Length of wooden frame = perimeter of the picture

=2 (l+b)

=2 (120+50)

=2 x 170

= 340 cm

Area of glass = area of picture

= l x b

=120 x 50

= 6000 cm^2

Hope it helps.........

Pls mark as brainliest!!!

Answer 2

Answer:Area  = 6000 cm

Step-by-step explanation:

Since length and breadth values are different , hence it is a rectangle .

Area  of rectangle is l*b

So , l=120 cm  b=50 cm(converted  length in meters into cm )

Area  = 6000 cm
