Question

can anyone send me the answer. ​

Answer 1

a = 2  cm  and b = 3 cm

so, (a+b) = (2+3) = 5 cm

a^2 = 4cm , b^2 = 9 cm , and ab= 6cm

(a+b)^2 = (2+3)^2 = (5)^2 = 25cm , 2ab = 2(2) (3)=12

therefore (a+b)^2 = a^2 + 2ab b^2

                               = 4 + 12 + 9

                                = 25cm
