find the area of a weird looking square with 2 mini squares coming out the front?

Question

the length is 6cm and width 10cm and the mini squares are 3cms

Answer 1

Without the figure, I assume you can calc the area separately and add them up

area of rect = 6 x 10 = 60
area of a 3 sq = 9
total = 60 + 2 x 9 = 78
