Answer:
27 feet
Step-by-step explanation:
We are told in the question that a lot is rectangular in shape
The perimeter of a rectangle
= 2(L + W)
= 2L + 2W
Where
L = Length of the rectangle
W = Width of the rectangle
From the question,
P = 66 feet
The length is 3 times more than 4 times the width
L = 3 + (4 × W)
= 3+ (4W) = 3 + 4W
Hence,
P = 2L + 2W
66 = 2(3 + 4W) + 2W
66 = 6 + 8W + 2W
Collect like terms
66 - 6 = 8W + 2W
60 = 10 W
W = 60/10
W = 6
The Width of the rectangular lot = 6 feet
To find the length
Perimeter = 2L + 2W
Perimeter - 2W = 2L
L = Perimeter - 2W/2
L = 66 - 2(6)/2
L = 66 - 12/2
L = 54/2
L = 27
Therefore the Length of the rectangular lot = 27 feet
Answer:
Step-by-step explanation:
First of all, I can't think of a single exception to this, but when you rotate a figure, the two figures are congruent If all you do is rotate it.
2y/2 = 5/2 Divide both sides by 2
y = 5/2
y = 2.5
2x = 67 degrees Divide both sides by 2.
2x/2 = 67/2 x = 33.5
3w + 3 =12 Subtract 3 from both sides
3w + 3 -3 = 12-3 Combine
3w = 9 Divide by 3
w = 9/3
w = 3
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be right if a² + b² = c²
<span>a. 13 35 37
13</span>² + 35² = 1394 and 37² = 1369
1394 ≠ 369
<span>b. 6 9 10
</span>6² + 9² = 117 and 10² = 100
117 ≠ 100
<span>c. 5 12 13
</span>5² + 12² = 169 and 13² = 169
169 = 169 ← <span> right triangle
</span>d. 9 40 42
9² + 40² = 1681 and 42² = 1764
1681 ≠ 1784
The answer is <span>c. 5 12 13</span>
Answer:
125
Step-by-step explanation:
You add all the breakdowns up together to get the total.
15+21+34+32+23 = 125
Answer: 354cm square
Step-by-step explanation:
18x20= 360
20-16=4
18-15=3
4x3/2=12/2=6
360-6=354
Hope this help :)
