Question

perimeter of a rectangle is 15 3/7m . If the length is 4 2/7m. Find its breadth

Answer 1

Answer:

HERE IS YOUR ANSWER..

Length is 4 2/7 = 30/7

perimeter is 15 3/7 = 108/7

LET BREADTH BE ... B

we know that ,,

perimeter = 2( length + breadth )

108/7 = 2( 30/7 + B )

108/7 = 60/7 + 2B

108/7 - 60/7 = 2B

78/7 = 2B

SO,,

B = 78/7*2

B = 39/7

I.E. ,,,

B = 5 4/7

OR.

B = 39/7
