Find, to the nearest tenth of a centimeter, the length of a diagonal of a square if the measure of one side is 8.0 centimeters.

Answer 1

Pythagorean Theorem

a^2 + b^2 = c^2

8^2 + 8^2 = c^2

64 + 64 = c^2

11.3 = c

Answer 2

The diagonal of a square measures 12 feet.
a. What is the exact measure of a side of the square?
b. What is the area of the square

Answer 3

Use the Pythagorean Theorem.

What do you get for the measurement of a side of the square?

Answer 4

I manage to get X^2+X^2=144

Answer 5

Right so far.

2x^2 = 144
x^2 = 72
x = 8.4852813

Each side = 8.4852813 feet

A = s^2
A = 72 square feet
