Question

THE PERIMITER OF A RECTANGULAR SWIMMING POOL IS 154 m. ITS LENGTH IS 2 M MORE THAN TWICE ITS BREATH ?​

Answer 1

Let the length of the pool be denoted by l , and the breadth be denoted by b

Then, the statement, “Its length is 2 m more than twice its breadth” is equivalent to writing:

l=2b+2

Now, for a rectangle, the perimeter, P, is given by:

P=2l+2b

Substituting our expression for l gives:

P=2(2b+2)+2b=6b+4=154

which we can re-arrange to find:

6b=150⟹b=25

And plugging this into our expression for l yields:

l=2b+2=2×25+2=52

Thus its length is 52m and its breadth is 25m

Answer 2

Answer:

thus it length is 52m and it's breath is 25m
