1. The figure below has been obtained by folding a rectangle. The total area of the figure (as visible) is 144 square meters. Had the rectangle not been folded, the current overlapping part would have been a square. What would have been the total area of the original unfolded rectangle?

Area of given figure = 144 sq meter It is given that BCE becomes square when we will unfold it, so to find the complete area of the figure shown as dotted after unfolding we need to add the area of triangle BCE. Thus, BC = CE = 6 m => Area of $$ riangle$$ BCE = $$frac{1}{2} imes 6 imes 6 = 18$$ sq meter $$ herefore$$ Final area of whole figure = 144 + 18 = 162 square meter.
