Question

Find the area of the figure. 5.3 in. 10 in. 4 in. 7 in.

Answer 1

First of all starting with finding the cut out lengths,
10-4=6
7-5.3=1.7

Area of that top left part of the diagram (imagine as if a square):
6*1.7/2=5.1

Area if that part was not cut:
7*10=70

Area of the entire diagram and final answer:
70-5.1=64.9
