Question

A picture is 1.2 m 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:

60m

1.2m=120cm,

its a rectangle

so, its area=lb

120*50=6000cm

6000cm=60m

Answer 2

Step-by-step explanation:

Given that;

Length=120cm & Breath=50cm

Therefore,

Length of Frame= 2(l + b) → 2(120 + 50)

So, Length of Frame= 2(170) → 340 cm

Now,

Required glass = Area of rectangle

So, Required glass= l×b → 120 × 50 = 6000cm²

Hence, the required area of glass is 6000cm² and the length of frame is 340cm
