Answer:
y = 6
Step-by-step explanation:
Given
6y - 2 = 34 ( add 2 to both sides )
6y = 36 ( divide both sides by 6 )
y = 6
K = LMN
We divide both sides by LN:-
M = K / LN
Answer: width = 280 miles, length = 380 miles
<u>Step-by-step explanation:</u>
width: L - 100
length: L
Perimeter = 2(Length) + 2(width)
1320 = 2(L) + 2(L-100)
1320 = 2L + 2L - 200
1320 = 4L - 200
1520 = 4L
380 = L
width: L - 100 ---> 380 - 100 = 280
length: L ---> 380
Step-by-step explanation:
Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)
area of triangle = 1/2 x 20 x (16-7) = 90cm^2
area of rectangle = 20 x 7 = 140cm^2
total area = 90 + 140 = 230cm^2

Answer:
400 cm squared
Step-by-step explanation:
Since a square has all equal sides, this would mean the the all the other sides are 20 as well. To get the area, you would just multiply 20 by 20 to get 400. :)
