Stomatal Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stomatal Index = (Stomata Per Unit Area/(Epidermal In Unit Area+Stomata Per Unit Area))*100
SI = (S/(E+S))*100
This formula uses 3 Variables

Variables Used

Stomatal Index - Stomatal Index is the number of stomata to number of epidermal cells.
Stomata Per Unit Area - Stomata Per Unit Area is the number of stomata per unit area.
Epidermal In Unit Area - Epidermal In Unit Area is the number of epidermal cells in the same unit area.

STEP 1: Convert Input(s) to Base Unit

Stomata Per Unit Area: 42 --> No Conversion Required
Epidermal In Unit Area: 36 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SI = (S/(E+S))*100 --> (42/(36+42))*100

Evaluating ... ...

SI = 53.8461538461538

STEP 3: Convert Result to Output's Unit

53.8461538461538 --> No Conversion Required

FINAL ANSWER

53.8461538461538 ≈ 53.84615 <-- Stomatal Index
