Question

Diagram of the adjacent picture frame has outer dimensions =24 cm x 28 cm
and inner dimensions 16 cm x 20 cm. Find the area of each section of
the frame, if the width of each section is same.
​

Answer 1

Answer:

Given,

Outer length of the frame =32cm and outer breadths =28c

Inner length =2cm and outer breadth =20cm

So, width of the frame =2(32−24)=4cm

Now, area of each portion of length side

=21×(24+32)×4

=21×56×4=112cm2

And,

Area of each portion of breadth side

=21×(20+28)×4

=21×48×4=96cm2

Therefore,

Area each section are 112cm2,96cm2,112cm2,96cm2
