Answer: 102.4 cm^2
Step-by-step explanation:
find the surface area of all of the rectangles
7.2(4)=28.8
7.2(2)=14.4
7.2(4)=28.8
7.2(2)=14.4
4(2)=8
4(2)=8
add
28.8+14.4+28.8+14.4+8+8=102.4

Given:
To find:
Answer:
Let's square the above expression.
According to the identities, (a - b)² = a² - 2ab + b². Using the same logic for the expression above,
Therefore, the value of x² + 1/x² is 27.
