Answer:
If the long side is down then the length of the base is 81 sq.m.
If the short side is down then the length of the base is 20.25 sq.m.
Step-by-step explanation:
162/4 is 40.5 that means if this were a square it would be 40.5 sq.m. On each side, if the base is longer you multiply 40.5 by 2 (or whatever youre supposed to honestl) and if the base is shorter you divide by 2 (or whatever you were supposed to)
The length and width of rectangular traffic sign are 40 and 30 inches respectively
<h3><u>Solution:</u></h3>
Given that,
Perimeter of rectangular traffic sign = 140 inches
Let length and width be denoted as ‘L’ and ‘B’ respectively
Given that length is 10 inches longer than its width
L = 10 + B
<em><u>The perimeter of rectangle is given as:</u></em>
Perimeter = 2( L + B)
On substituting the values, we get
140 = 2(10 + B + B)
140 = 2(10 + 2B)
140 = 20 + 4B
B = 30
Therefore, the length is L = 10 + 30 = 40
Hence the dimensions length and width of the rectangle are 40 and 30 inches respectively.
Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.
4x + 4 = 6x - 14
Subtract 4x from both sides.
4 = 2x - 14
Add 14 to both sides.
18 = 2x
Divide both sides by 2.
x = 9.
Because we have a constant value of x, we can solve for BC.
BC = 2x + 7
2(9) + 7
18 + 7
25
<h3>The value of BC is 25.</h3>
For this case we have:
Note:<em> Milliliter is a unit of volume. It is not possible to convert distance units into volume units.
</em>
We must convert the length 0.13 meters to millimeters.
By definition, 1 meter equals 1000 millimeters. That is to say:
Then, applying the rule of three we have:
1m ------------> 1000mm
0.13m --------> x
Where x represents the length of the marker in millimeters.
Resolving:
Thus, the marker measures 130 millimeters long
Answer:
130 millimeters
I think answer should be 8 please give me brainlest let me know if it’s correct or not okay thanks bye
