Answer:
The length is 14 m.
Step-by-step explanation:
length = L
width = W
perimeter = P
"The perimeter of a rectangle is twice the sum of its length and its width."
P = 2(L + W)
"The perimeter is 40 meters"
40 = 2(L + W)
"and its length is 2 meters more than twice its width."
L = 2W + 2
Replace L with 2W + 2 in equation 40 = 2(L + W):
40 = 2(2W + 2 + W)
40 = 2(3W + 2)
20 = 3W + 2
3W = 18
W = 6
The width is 6 meters.
L = 2W + 2 = 2(6 m) + 2 m = 12 m + 2 m = 14 m
Answer: The length is 14 m.
Y-y1=m(x-x1)
Thru that, you get:
y-4 = 3(x-2)
Answer:
$169.65 is the total cost
Step-by-step explanation:
A= πr2= π·6(2)≈ 113.1
113.1 * 1.50 = 169.65

Answer:
Step-by-step explanation:
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of the 2 parallel sides or bases of the trapezoid. Since it is an isosceles trapezoid, then the length of the 2 legs are equal.
h represents the height of the trapezoid.
From the information given,
Area = 45cm²
h = 5 cm
45 = 1/2(a + b)5
2 × 45 = 5(a + b)
90 = 5(a + b)
a + b = 90/5 = 18
if one of the legs is 2/3 of the sum of the bases, it means that the height of each leg is
2/3 × 18 = 12 cm
The length of both legs is
12 × 2 = 24 cm
The perimeter of the trapezoid is
Sum of bases + sum of legs
Therefore,
Perimeter = 18 + 24 = 42 cm
