Question

The outer length and breadth of a painting is 150cm*120cm.If there is a margin of 8cm width all around the painting, find the area of the acute panting (without margin). ​

Answer 1

Answer:

The dimensions of the rectangular painting ,

Length =L=150cm

Breadth =B=120cm

According to the problem,

The width of the marigin around the painting =w=8cm

Now , the diminsions of the actual painting are

Length of the actual painting =l=L−2w

l=150−2×8

l=150−16

l=134cm

Breadth of the actual painting =b=B−2w

b=120−2×8

b=104cm

Therefore,

Area of the actual painting =l×b

=134cm×104cm

=13936squarecm
