width: w
length: w+4
2(w + w+4) = 84
Now just solve for w and calculate w+4.
length of a rectangle exceeds its breadth by 4 m. if the parimeter of the the rectangle is 84 m, find its length and breadth.?

length=23 and width=19
Math
Perimeter formula = 2(l+b)
Length and breadth according to question=x,x+4
2(x+x+4)=84
2x+2x+8=84
4x+8=84
4x=84-8
4x=76
x=76รท4=19
Breadth=x=19
Lenght=x+4=23
