Question

the perimeter of a rectangle Is 154m.its length is 2m more than twice its breadth .what are the length and breadth of the rectangle ​

Answer 1

Answer:

don't know sorry..................

Answer 2

Answer:

Let the length of the pool be denoted by ll, and the breadth be denoted by bb

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

l=2b+2l=2b+2

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

P=2l+2bP=2l+2b

Substituting our expression for ll gives:

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

which we can re-arrange to find:

6b=150⟹b=256b=150⟹b=25

And plugging this into our expression for ll yields:

l=2b+2=2×25+2=52l=2b+2=2×25+2=52

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