9. area of one traingle will be  = 1/2*2.8*4 = 5.6 in^2

       5 such triangles will form the pentagon so, area  = 5*5.6 = 28 in^2



10. area of hexagon be divided into 6 equilateral traingles,

area of 1 equilateral triangle = sqrt (3)/4 * 20 = 5*sqrt 3 = 173.21 cm^2

so, area of hexagon = 6*173.21 = 1039.3 cm^2
