Answer:

A = 119 units²

Step-by-step explanation:

side of square is (12√2)sin45 = 12

The portion of the diagonal that is NOT octagon is

12√2 - 12

There are four corner triangles. The sum of their areas is

(12√2 - 12)²

Area of the octagon is area of the square minus four corner triangle areas.

A = 12² - (12√2 - 12)²

A = 119.2935...

How do you use ratio to compare mass

BartSMP [9]

Apply the law of multiple proportions to the two compounds. For each compound, find the grams of copper that combine with 1.00 g of chlorine by dividing the mass of copper by the mass of chlorine. Then find the ratio of the masses of copper in the two compounds by dividing the larger value by the smaller value.
