There is secretly a rectangle and a square. The rectangle is at the bottom and the square is at the top.
rectangle: The bottom of the rectangle measures 9cm. The sides measure 2cm; 9x2=18 The rectangle measure 18.
Square: The top measure 6cm. The side measures 5cm. 5x6=30 So now you add everything together. 30+18=48
You could find the rectangle and the square by just creating a simple line. Some of the numbers don’t matter for example 3cm and 7cm didn’t matter in this situation. Hope this helped!!
SHAPE A: The larger one. We can infer the size of the bottom is 6 cm because it's the same size as it's top counterpart. Same goes for the left side, which will have a measure of 7 cm.
SHAPE B: The smaller one. We're going to use the same method as we did with the first one, and infer the lengths of the other sides using the existing ones.
To calculate area, it's length times width.
SHAPE A: Its two side measures are 6 and 7, which equates to 42 cm^2.
SHAPE B: Its two side measures are 2 and 3, which equates to 6 cm^2.
