Square root of the summation(RMS)

I want to get the results base on the square root of the summation of (square of (height * width).

Example data set ; Height = 40 Width = 0.5

Could you please give me a code for this problem?

This is not the conventional meaning of RMS, which is the square Root of the Mean of the Squares. Also, this is a pretty basic calculation, what have you tried already? Since your example data has only scalar values, it seems strange to ask for a sum. What is the sum of a single value?

height = 40:60;
width= linspace(0.2,0.5,length(height));
sqrt(sum((height.*width).^2))

Why use length, instead of numel? And why do you not store the result of the third line of code in a variable?
