Answer:
let 3:2 be 3x& 2x
perimeter =40
2(l+b)=40
2(3x+2x)=40
5x=40/2
x=20/5=4cm
length=3x=3×x=3×4=12cm
breadth =2x=2×4=8cm
area of rectangle =l×b=12×8=96cm²
In this question we can see
that there is one unknown variable named “y” and one equation. So it is
absolutely possible to find the correct value of the unknown variable “y”. Now
let us check the equation that is given and solve it correctly.
y - 18 = 10
y = 10 + 18
= 28
So the value of the unknown variable “y” is 28. I hope this
is the answer you were looking for and the procedure is clear to you.
Left and right side are exactly same, therefore "<span>the equation is true for any value of x.</span>"
