Answer:
190 ft^2
Step-by-step explanation:
So first we need to find which equation we're using and since it's a rectangular prism we're going to use:
2Lw + 2wh + 2Lh
Now what we need to do is plug in the values
2*9*2 + 2*2*7 + 2*9*7
Now just multiply everything and then add it together.
36 + 28 + 126
Once you add everything together you get:
190
The question says to include the correct unit. It says that its feet, but we need to know if its feet squared (^2) or cubed (^3)
If it were area of the whole object, it would be cubed because it is all the area that the object takes up but since it's just the area of the surface it's going to be squared. Therefore, the answer is:
190 ft^2
Answer:
1) 13 ft.
2) 23.3 m (when rounded to 1 dp)
Step-by-step explanation:
The Pythagorean theorem states that when a and b are the two legs (the sides adjacent to the right angle) and c is the hypotenuse (the longest side). This only applies to right triangles.
<u>1) Question 1</u>
The lengths of the two legs in the image are 12 ft. and 5 ft. We know that these are the legs because they are the sides adjacent to the right angle. We're solving for the length of the ladder, which in this case would represent the hypotenuse (c). Plug the values 12 and 15 into the equation as a and b and solve for c:
Take the square root of both sides
Therefore, the length of the ladder is 13 ft.
<u>2) Question 2</u>
The lengths of the legs in the image are 20 m and 12 m. Again, we know that these are the legs because they are the sides adjacent to the right angle, which in this case would be the corner of the garden. We're solving for the length of the fence going diagonally from one corner to the other, which represents the hypotenuse (c). Plug the values 20 and 12 into the equation as a and b and solve for c:
Take the square root of both sides
Therefore, the length of the fence when rounded to 1 decimal point is 23.3 m.
I hope this helps!
Put 10 where n is, then do the arithmetic.
