Answer:
60cm²
Step-by-step explanation:
as the green and blue box are squares they will have the same sides, length.
so all the sides in the green and blue squares are 3
the pink and orange rectangles : the longer is 7 the shorter one is 3
for the top length of the whole shape is = 7 +3 = 10
side length of the shape is 3 + 3= 6
so then you do 6 x 10 = 60
60 cm² is the answer :)
