14.The figure below represents a plotbounded by two straight edgesand a semi-circle.12 m90°16 mWhat is the area of plot?(Take n = 3.14)A. 724 m2B. 150.72 m2C. 410 m2D. 253 m?

Answer»

The other side of triangle or diameter will be= √144+256= √ 400= 20 cmarea of plot will be area of triangle + area of half circles= 20+12+16= 48/2= 24now area= √ 24(24-12)(24-20)(24-16)√24*12*4*8√24*12*3296 m^2nowarea of semicircle= 1/2*10*10*3.14= 157now total area= 157+96253m^2
