• geometry String area|circumference
• dimensions Array [numbers]

Required arguments for dimensions by shape and geometry

• Area of triangle [base, height]
• Circumference of triangle [sideA, sideB, sideC]
• Area of rectangle [base, height]
• Circumference of rectangle [base, height]

totalAreaMultipleShapes(shapes)

Calculates the total area of shapes provided

Required argument

• shapes Array [Objects]

Required keys for each shape

• shape String triangle|rectangle|circle
• dimensions Array [numbers]

Required arguments for dimensions by shape

• Area of triangle [base, height]
• Area of rectangle [base, height]

Example

var GCN = require('gcn_sample'),
    gcn = new GCN(),
    triangle = {
      shape: 'triangle', geometry: 'circumference', dimensions: [5, 5, 5]
    },  
    circumferenceOfTriangle = gcn.calc(triangle),
    multipleShapes = [
      {shape: 'triangle', dimensions: [6, 6]},
      {shape: 'rectangle', dimensions: [10, 10]},
      {shape: 'circle', dimensions: [5]}
    ],
    totalArea = gcn.totalAreaMultipleShapes(multipleShapes);
