To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:
2 x 2 = 4
8 x 8 = 64
64 + 4 = 68
Your answer should be 68 ft.^2
If we use the rules we say that <span>when we multiply two numbers we get the result in the numbers the least significant number has in the multiplication. So we may proceed like this:</span>
67.6 x 1.2 = 81.12
<span>As the decimal part does not continue indefinitely we can leave the answer as it is.</span><span> if the answer was 81.123612356213 then we leave it like </span><span>81.1 as the rules say</span>
Answer: The mat is 4.33 ft high off the ground.
Step-by-step explanation:
Since we have given that
Angle of elevation with the first triangle = 30°
Angle of elevation with the second triangle = 60°
Length at which gymnastics mat extends across the floor = 5 feet
so, As shown in the figure:
We need to find the height of the mat off the ground.
If CD = 5 ft,
Let, AB = y, DC = x.
In Δ ABC,
Similarly, in Δ ACD,
Hence, the mat is 4.33 ft high off the ground.
Step-by-step explanation:
multiplication cause gives a reasonable answer.
