The value of A is 31.5.
The square root of any number is the factor that we can be multiplied by itself to get that given number. The symbol for square root is √.
Here, we are given an equation as follows-
A=√[15.5(15.5-14) (15.5-11) (15.5-6)]
Let us simplify it step by step. Firstly, we will perform the operations inside the brackets as follows-
A = √[15.5(1.5) (4.5) (9.5)]
Now, multiplying the terms we get-
A = √[15.5(1.5) (4.5) (9.5)]
A = √[(23.25) (42.75)]
A = √[(993.9375)]
Now, we calculate the square root of the number obtained above-
A = 31.5
Thus, the value of A in the equation A=√15.5(15.5-14) (15.5-11) (15.5-6) comes out to be 31.5.
