Q3 of 26 Page 25

The diagonals seg DF and seg EG of the square DEFG intersect each other in point M. If l(DM) = 7 cm, find l(EG).

The figure is given below:



As we know that diagonals of square are equal and bisect each other


i.e. Diagonal DF = Diagonal EG [equal diagonals]


AND DM = MF [diagonals bisect]


DF = DM+MF


DF = 2× DM = 2× 7cm ×


DF = 14cm


If Diagonal DF = EG


EG = 14cm
