Question

The ratio of the length and the breadth of a rectangle is 4:3 and the area of the rectanlge is 6912

Answer 1

Given length and breadth ratio is 4:3
to find length and breadth
so let length be 4x then breath = 3x
according to question area is given as 6912
and we know that length ×breath=6912
so,4x×3x=6912
12xsquare=6912
xsquare=6912/12
xsquare=576
X=√576
X=24
so, length=4×24=96
and breadth= 3×24=72

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

=>6912= 12x^2 =
=> 6912/12=x^2
=> 576=x^2
=>24=x

length = 4x =4×24=96
and breadth = 3x = 3×24=72

perimeter of the rectangle = 2 (l + b)
=> 2× (96+72)
=>336cm

Area of rectangle =l×b
=>96×72=6912m^2

Ratio of breath and rectangle =72/6912=3:288

hope it helps you
