How is the hexagon represented by simpler polygons and what are the dimensions of each of these polygons(b)find the are of the complex polygongs. left side is 7ft top is 20ft right side is 6ft base is 24 ft

There are two ways in order to represent hexagon as simpler polygons. (1) use 6 triangles with a common vertex at the center (or anywhere inside) of the polygon, (2) Use four-sided polygon with shared sides and vertices still inside the polygon. 

(b) Unfortunately for b, it would have helped us in finding the area of the complex polygon if a figure is shown. 

2380 units²

Step-by-step explanation:

Thinking process:

let the length be z = 25 ft

let the breadth be  x = 20 ft

let the height be y = 15 ft

surface area  = 2 (lb) + 2 (lh) + 2 (bh)

                      = 2 (25 ×20) + 2 (25 × 15) + 2 (20*15)

                      = 1000+ 750 + 600

                      = 2350 units²

By increasing the rates by 0.1 ft/sec, 0.2 ft/sec, and 0.5 ft/sec respectively, gives 2380 units²
