Answer: (D) 7
Step-by-step explanation:
The area which is not in used for the flower gardens is 10964 sq ft.
Step-by-step explanation:
Given,
Length (l) of the rectangular park = 160 ft
Width (b) of the rectangular park = 80 ft
Length (l) of each rectangular flower garden = 18 ft
Width (b) of each rectangular flower garden = 17 ft
To find the area which is not in used.
Formula
The area of rectangle = l×b
Now,
The area of the rectangular park = 160×80 sq ft = 12800 sq ft
The area of each rectangular flower garden = 18×17 sq ft = 306 sq ft
The area of 6 rectangular flower garden = 306×6 sq ft = 1836 sq ft
So,
The area which is not in used = 12800-1836 sq ft = 10964 sq ft.
EK=6, KF=6
By the Pythagorean theorem
EF≈8,48≈8

Answer:
n = 11
Step-by-step explanation:
The side length of a triangle are n,n-3 and 2(n-2).
The perimeter of the triangle, P = 37 units
We need to find the value of n.
Perimeter = sum of all sides
n+n-3 +2(n-2) = 37
2n-3+2n-4 = 37
4n -7 = 37
4n = 37+7
4n = 44
n = 11
So, the value of n is 11.
