Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
now, let's bear in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
so, let's multiply both sides by the LCD of all fractions, that way we do away with the denominators.
Answer:
c = 11.03 m
Step-by-step explanation:
In this given <em>right isoceles triangle</em>, one of the sides are labeled as 7.8 m. We'll label this side as "a."
The length of side "a" is congruent to the other side. Therefore, the measurement of the other side is also 7.8 m.
We can use the Pythagorean Theorem to solve for the measurement of the hypotenuse, side "c."
According to the Pythagorean Theorem: .
We'll plug in the values for side "a" and side "b" into the formula:
To calculate the value of "c," we must take the squared root of :
c = 11.03087 m or 11.03 m
By the way, the value of c = <em>a </em>
Answer:

Step-by-step explanation:
Well it asks what's the perimeter of the ACTUAL region. So it should be 22.4 times 200. (If I read it right)
11. To find the scale factor: 10 / 5 = 2
scale factor: 2
To find the side: 12 / 2 = 6
Answer: 6ft
12. To find the side: 8 / 6 = 1.3
scale factor: 1.3
To find the side: 18 / 1.3 = 13.8
Answer: 13.8 ft
13. To find the side: 18 / 6 = 3
scale factor: 3
To find the side: 8 / 3 = 26
Answer: 24ft
