given --
(1.75×1.75 - 0.25×0.25) / (1.25+0.25) =3m
(1.75^2 - 0.25^2) / (1.5) =3m
by using property (a^2-b^2) = (a-b) (a+b)
(1.75 - 0.25)(1.75 + 0.25) / 1.5 = 3m
1.5 × 2 / 1.5 = 3m
3m =2
m = 2/3
(1.75×1.75 - 0.25×0.25) / (1.25+0.25) =3m
(1.75^2 - 0.25^2) / (1.5) =3m
by using property (a^2-b^2) = (a-b) (a+b)
(1.75 - 0.25)(1.75 + 0.25) / 1.5 = 3m
1.5 × 2 / 1.5 = 3m
3m =2
m = 2/3
