For each one just use given info to solve area equations of each square then add them up.
5) bottom bigger square with dimensions 5 by 12
A = base * height
A = 60
Now for the top part, we know that the bottom square uses 5 cm of that 10 cm long vertical
So 10-5 = 5 for height and the base is given as 4cm
A = 4*5 = 20
So 20 + 60 = 80 square cm
6) bottom bigger is 5 by 3
A= 15
The top smaller is 1 by 2
A= 2
So area is 15+2 or 17 square cm
7) again bottom big is 11 by 5
A = 5*11 = 55
The smaller left top is 7-5 or 2 height
So dimensions are 1 by 2
A = 1*2 = 2
55 + 2 = 57 square cm
Clearly they are not drawn to scale but that’s the answers
