Let's assume width of a rectangle= a inches
than length of the rectangle = 2*a + 2
= 2a+ 2 inches
perimeter of the rectangle. = 70 inches
perimeter (P) = 2(length+ width)
after substituting value of l and w we have
p = 2(l+w)
70= 2( 2a+2+ a)
70= 2(3a+2)
70= 6a+4
70 - 4= 6a
66= 6a, a= 66/6= 11
so a=11 inches, a= width
therefore width is = 11 inches
length is = 11*2+2= 24 inches
Answer:
78
Step-by-step explanation:
Because a^2+b^2=c^2. So 900 plus 5184, then you find the square root.
Answer:
13.2 miles
Step-by-step explanation:
To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.
(5.5 + 3.5)² + b² = 15²
9² + b² = 15²
81 + b² = 225
b² = 144
b = 12
Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).
5.5² + 12² = c²
30.25 + 144 = c²
174.25 = c²
13.2 ≈ c
Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.
