the length and breadth of the rectangle are in the ratios 4:3. if the diagonal measures 25 cm, find the perimeter of rectangle

Solution:

Let the length of rectangle = 4x and its breadth = 3x

Diagonal of the rectangle = 25 cm

In a rectangle,

Diagonal^{2} = Length^{2}

Let the length of rectangle = 4x and its breadth = 3x

Diagonal of the rectangle = 25 cm

the smallest no divisible by 12, 15, 20 and is a perfect square

12 = 2 x 2 x 3

15 = 3 x 5

20 = 2 x 2 x 5

So, LCM = 2 x 2 x 3 x 5 = 60

As 3 and 5 are not in pair in LCMâ€™s factor so we need to multiply 60 by 5 ...
