Answer 2

Answer:

Step-by-step explanation:

5 . ABCD is a square

AB = BC = 1.2cm

Join AC now in triangle ABC

Angle B = 90°

So ar of ABC =1/2*AB*BC= 1/2*1.2*1.2cm^2

ar of ABC =0.72cm^2

Also ar of CDA = ar of ABC = 0.72cm^2

Total area of ABCD = ar of ABC + ar of CDA = (0.72+0.72)cm ^2

Ar of ABCD = 1.44cm ^2
