Question

length of a rectangle is 2 centimetre more than twice its breadth if the perimeter of the rectangle 28 cm find its length and breadth

Answer 1

Hey Mathematicians,

Let the breadth be x.
Length will be 2x+2

We know,
Perimeter of a rectangle=> 2[l+b]

28=2[(x)+(2x+2)]
28=2[x+2x+2]
28=2[3x+2]
28=6x+4
28-4=6x
24÷6=x
4=x

Therefore, the breadth is 4 cm and the length will be:-
2x+2=2(4)+2=10

Length will be 10cm.
