Length = 60; Width = 36
The formula for Perimeter is P = 2L + 2W
Where L = length; W = width
192 = 2L + 2W
= 2(5x) + 2(3x)
= 10x + 6x
= 16x
192/16 = 16x/16
x = 12
Substitute the values:
192 = 2(5x) + 2(3x)
= 2(5*12) + 2(3*12)
= 2(60) + 2(36)
192 = 192
Answer:
1. 4
2. 35
3. Her yard is a rectangle. She needs a 3000 feet of fence.
Step-by-step explanation:
1. The length of one side is 5 - 3 = 2 (subtract the y values)
The length of the other side is 7 - 3 = 4 (subtract the x values)
So the area is 2*4 = 8
2. The length of one side is 6 - 3 = 5 (subtract the x values)
The length of the other side is 7 - 0 = 7 (subtract the y values)
So the area is 5 * 7 = 35
3. The shape of her yard is a rectangle.
The length of one side of the fence is 5 - 0 = 5 units (subtract the x values)
The length of the other side of the fence is 10 - 0 = 10 units (subtract the y values)
The perimeter would be
(2*5) + (2*10)
= 30 units
Since the distance between each unit plotted is 100 feet, the total amount of fence needed would be
30 * 100
= 3000 ft
Answer:
74.6 m
Step-by-step explanation:
First look at the rectangle, which is 15 meters wide horizontally and 18 meters long vertically. This rectangle contributes 2(18 m) + 15 m to the perimeter (the 15 m side is the bottom of the figure). That comes to 2(18) m + 15 m, or 51 m.
Next, look at the semicircle. Its diameter is 15 m and thus its total circumference is approximately (3.14)(15 m), or 47.1 m. We take only half of this circumference in calculating the perimeter of this figure: 23.6 m.
The total perimeter of this figure is 23.6 m + 51 m, or approximately 74.6 m.
Answer:
p = 8
Step-by-step explanation:
Let one root of the eqn. be alpha . Other root is 1/alpha .
We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant & "a" is the co-efficient of x^2.
Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )
