What is the total area of the surfaces of both tables?

2 answers:

7 0

There are two equal tables.
We need to add bases and multiply that by the height divided by two.
7+3=10•1=10
Now multiply that by two since there are two tables.
10•2=20

So, the tables area are 20 feet squared.

Answer: $\bigg(n+\dfrac{5}{4}\bigg)^2$

<u>Step-by-step explanation:</u>

$n^2+\dfrac{5}{2}n+\underline{\qquad}\\\\\\n^2+\dfrac{5}{2}n+\bigg(\dfrac{5}{2\cdot 2}\bigg)^2\\\\\\n^2+\dfrac{5}{2}n+\bigg(\dfrac{5}{4}\bigg)^2\\\\\\=\bigg(n+\dfrac{5}{4}\bigg)^2$
