Find the length of a side of a square with an area of 169 in^2.
Answer:
D. 13 in
Step-by-step explanation:
A square has sides of equal length.
A = L^2 where: A = area and L = side
L^2 = 169
L=√169
L=13 in^2.

This is because on the periodic table, it shows that Boron has 5 protons and 5 electrons
Answer:
Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>

Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
All you do is add up all your sides! So if your shape has 4+4+5+5 = 18. All you do is add them up!
