Question

area of a rectangle whose length and breath is the ratio 3:2 is 1045.44 cm.cube .find the dimension of rectangle

Answer 1

As the length and breadth of the rectangle are in the ratio 3:2
Let them be 3x and 2x respectively,
Then,
3x*2x = 1045.44
6x^2 = 1045.44
x^2 = 174.24
x = 13.2
Therefore, Length = 3*13.2 = 39.6 cm
Breadth = 2*13.2 = 26.4 cm. Ans.

Answer 2

Hey!! Here is your answer u r looking for..

let the ratio contain x
l=3x
b=2x
Area of rectangle = l×b
1045.44 =3x × 2x
6x^2 = 1045.44
x^2 = 1045.44 / 6
x^2 =174.24
x = 13.2cm

Now, l=3x = 13.2 × 3 =39.6
b= 2x = 13.2 × 2 =26.4
