- 6912=4x*3x
6912=12x*x
X^2 = 576
X = 24
6912=3*x
6912=72
72/6912 = 1 : 96 - 4 years agoHelpfull: Yes(4) No(0)
- given l/b=4/3,
so l=4b/3
and area=lb=6912,
[4b/3]b=6912
b^2=5184
b=72
b/area=72/6912
=1:96
option(A) - 2 years agoHelpfull: Yes(2) No(0)
- l*b=6912
l/b=4/3
l=4*b/3
b^2=6912*3/4
b=72
72/6912=1/96=1:96 - 4 years agoHelpfull: Yes(0) No(0)
- area of rectangle=l*b
4x*3x=6912
x=24
breadth=24*3=72
breadth:area of a rectangle=72:6912=1:96 - 3 years agoHelpfull: Yes(0) No(0)
- Area=3x *4x =12x^2
6912=12x^2
X=24
the ratio of breadth and area=3x/12x^2=1/4x=1/4*24=1/96 - 3 years agoHelpfull: Yes(0) No(0)
- let ratio be 4x:3x
area of rectangle=4x*3x=12x^2=6912
x=24
then breadth=3*24=72
ratio=72/6912=1:96 - 3 years agoHelpfull: Yes(0) No(0)
- 4x*3x/12x=1/4x
x=96
1:96 - 2 years agoHelpfull: Yes(0) No(0)
- A)1 : 96
we can find the actual value of length and breadth by taking area of rectangle formula
so, Breadth=72, therefore 72:6912 = 1:96 - 1 year agoHelpfull: Yes(0) No(0)
- Area = Lxb
area = 4x X 3x = 6912
x = 24
b = 72
area/breadth = 1 : 96 - 9 Months agoHelpfull: Yes(0) No(0)
- Assume const k
4k * 3k = 6912
12k*2 = 6912
K =24
24*3:6912=1:96 - 8 Months agoHelpfull: Yes(0) No(0)
