Answer:
Step-by-step explanation:
area of a rectangle = length × breadth
let lenght be x and breadth be y
area = x× y
Area is given 144 sq cm
144= xy.
y=144/x ...1
perimeter of a rectangle = 2 ( x+y)
Now using the value of y from equation 1
perimeter = 2 ( x + 144/x)
= 2( x^2 +144)/x
The question stops here. we need a hint to proceed further.
