Question

Find the area of the complete figure provided that the figure given below represents a half across the line of symmetry and each square block corresponds to 1 sq. cm.

Answer 1

Area of the figure given can be calculated by the number of squares it covers.
Area of the half figure given across the line of symmetry = $10{\mathrm{cm}}^2.\mathrm{Area}\mathrm{of}\mathrm{the}\mathrm{complete}\mathrm{figure}=(2\times 10){\mathrm{cm}}^2=20{\mathrm{cm}}^2$
