Answer:
the area is 43cm²
Explanation:
First, you find the area of the left side. 7cm - 3cm= 4cm
Secondly, you multiply 4cm x 4cm = 16cm
Then, you find the area of the bottom bit. 9cm x 3 cm = 27cm
Lastly, you add 27cm + 16cm, which brings your answer to...
43cm² :-)
(It's squared because you are finding the area)
