Answer» Given a red carpet with dimensions Length = 12 m Width = 1.5 m Now, A 10 cm wide border runs parallel to the lengths on both the edges.Along the width of one edge the border is 25 cm wide and on the other side the border is .5 m broad with WELCOME' inscripted ón it. We have to find total area of border Area = Area (1) +Area(2)+Area(3)+Area(4) = 0.5*1.5+11.25*0.1+0.25*1.5+11.25*0.1+0.75+1.125+0.375+1.125=3.375m^2 Hence, the total area of border is 3.375m^2 |
