Problema Solution
Determine the dimensions of a rectangle with perimeter 100cm, if lenght is 4cm longer then it's breadth
Answer provided by our tutors
let
l = the length of the rectangle
b = the breadth of the rectangle
P = 100 cm the perimeter of the rectangle
P = 2 (l + b) is the formula for perimeter thus we have
2(l + b) = 100 divide both sides by 2
l + b = 50
the lenght is 4cm longer then it's breadth
l = b + 4
by solving the system of equations
l + b = 50
l = b + 4
we find
l = 27 cm
b = 23 cm

the length is 27 cm and the breadth is 23 cm.
