The local town is planning to build a highway that will intersect the borders of the field at points D and E, where DC 210m and CED= 100, as shown in the diagram below. %3D diagram not to scale A highway 650 210 100 C. B (b) Find DE. The town wishes to build a carpark here. They ask the farmer to exchange the part of the field represented by triangle DCE. In return the farmer will get a triangle of equal area ADF, where F lies on the same line as D and E, as shown in the diagram above. (c) Find the area of triangle DCE. (d) Estimate DF. You may assume the highway has a width of zero.
