Question

5. A picture frame is 36 cm long and 30 cm broad. The part of the frame surrounding the
picture is 4 cm wide on all sides. Find the length and breadth of the space for the picture.
What is the area of this space?
36 cm​

Answer 1

Answer:

Step-by-step explanation:

Length of outer part of picture frame = 36cm

Breadth of outer part of picture frame = 30cm

Therefore, area of outer part of picture frame =

l x b

= 36 x 30

= 1080 cm^2

Length of inner part of picture frame = 36 - 4 = 32cm

Breadth of inner part of picture frame = 30 - 4 = 26cm

Therefore area of inner part of picture frame = l x b

32 x 26

= 832 cm^2

Now, area of space inside picture frame = 1080 - 832 = 248 cm^2

Answer 2

Answer:

Length=36cm

Breadth=30cm

Area of frame= 36×30

                      =1050cm²

Side of space of picture=4cm

Area of space for the picture=4×4

                        =16cm²

Area of picture= 1050-16

                        =1034cm²
