Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.

Household supply of 230volts is rms value or maximum value of voltage?
When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
How do you measure rms value of complex waveform?
rms value is measured using voltmeter with the use of heat sensing elements.

Which has a higher RMS value given a sine wave a square wave and a sawtooth wave?
A square wave has the highest RMS value. RMS value is simply root-mean-square, and since the square wave spends all of its time at one or the other peak value, then the RMS value is simply the peak value. If you want to quantify the RMS value of other waveforms, then you need to take the RMS of a series of equally spaced samples. You can use calculus to do this, or, for certain waveforms, you can use Cartwright, Kenneth V. 2007. In summary, the RMS value of a square wave of peak value a is a; the RMS value of a sine wave of peak value a is a divided by square root of 2; and the RMS value of a sawtooth wave of peak value a is a divided by cube root of 3; so, in order of decreasing RMS value, you have the square wave, the sine wave, and the sawtooth wave.

Does a volt meter read rms?
Yes, if it is set to measure AC, it is usually calibrated to RMS.

Is utility voltage ie 110 VAC given as a RMS value or as a Peak value?
All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.
Why do we need exactly one cycle data for computing the RMS value?
You don't need exactly one cycle data for computing the RMS value. It is just a convenient normalization. 1 cycle = 1Hz. RMS values can also be specified in 1 Mcycle, 1kcycle, even 2.39384kcycles. Again, 1 cycle is simply convenient. In other words, if the RMS value were specified in MHz, the RMS value will be 20*log(MHz/Hz) higher.
