Question

Find the perimeter of the rectangle whose area is 144 CM square

Answer 1

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.
