Question

the ratio of the length and breadth of a rectangle is 4:3 and the area of the rectangle is 1728sq.what is the ratio of the breadth and area of the rectangle?

Answer 1

let d ratio be 4x & 3x
4x*3x=1728
12x^2=1728
x^2=144
x=12
ratio of breadth & area =3*12/1728=1:48.

Answer 2

Here is your solution

Given :-

The ratio of length and breadth of the given rectangle is 4:3

Let the length and breadth be 4x and 3x .

as area of rectangle = length × breadth

=>1728= 12x^2 =
=> 1728/12=x^2
=> 144=x^2
=>12=x

length = 4x =4×12=48
and breadth = 3x = 2×12=24

perimeter of the rectangle = 2 (l + b)
=> 2× (48+24)
=>120cm

Area of rectangle =l×b
=>36×24=864m^2

Ratio of breath and rectangle =24/864=3:108

hope it helps you
