Hello!
6.
Since the area is that of a square, you know that all side lengths are the same.
Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².




The length of the side of a square with an area of 144 in² is
12 in.

Rational number.

This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.
Plug in your leg lengths:
a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4
Answer:
5/6
Step-by-step explanation:
1/6 + 1/6 = 2/6 TYPE A wood
1/4 + 1/4 = 2/4 TYPE B wood
2/6 + 2/4= ...
2/4 reduces to ?/2
That would be 1/2 because 4 divided by 2 is 2 & 2 divided by 2 is 1.
1/2= ?/6
Its 3/6 because we did 2 x 3 to get 6 and we do the same to the number 1. So we do 1 x 3 = 3
Now we have 3/6 + 2/6!
This is very easy now! We just do 2 + 3 which gets 5.
OUR ANSWER IS 5/6!! Hope this helps! plz mark as brainliest!
