Question

A picture frame is 36 cm long and 30 cm broad the part of the surrounding the picture is 4 cm wide on all sides find the length and breadth of this is space for the picture what is the area of this side

Answer 1

Answer:

248 cm^2

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
