Answer:
3÷2
Step-by-step explanation:
First let the required no. be 'x'.
By question,
(2÷3)+2x=3x-(5÷6)
or,(2+6x)÷3=(18x-5)÷6
or,2+6x=(18x-5)÷2
or,4+12x=18-5
or,x=9÷6
Therefore, x=3÷2

Let s represent the length of any one side of the original square. The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.
The area of this rectangle is (s+9)(s-2) = 60 in^2.
This is a quadratic equation and can be solved using various methods. Let's rewrite this equation in standard form: s^2 + 7s - 18 = 60, or:
s^2 + 7s - 78 = 0. This factors as follows: (s+13)(s-6)=0, so that s = -13 and s= 6. Discard s = -13, since the side length cannot be negative. Then s = 6, and the area of the original square was 36 in^2.
84/60=1.4
210/1.4=150
The answer is 150 cm
