Area of decagon is given by: Area=1/2(nsr) where: n=number of sides s=side length r=height thus the area will be given by: Area=1/2(10*4*6.2) Area=124 cm^2
if the length of each side is 16in, the total length would be 32in. (16 x 2 = 32) because the length is equal to twice the width, divide 32 by 2 (32/2 = 16)
