For this case we have that by definition, the perimeter of the quadrilateral shown is given by the sum of its sides:
Let "p" be the perimeter of the quadrilateral, then:
So, the perimeter of the figure is:
Answer:
So to find the answer we need to know the area of the deck by splitting each individual part into smaller shapes.
So for the rectangle up top we have: 50ft
Then for the triangle: 12.5ft
Then another rectangle above the triangle which is: 50 ft
Then the biggest rectangle is: 375ft
We would add this all together.
50+50+375+12.5=487.5
So one gallon costs $34 and covers 200 ft
So 487.5/200=2.437->multiply it by 34 and get 82.8 or $83
Your answer is $83
Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
Your answers should be, the first one 1. (3.1)(3.1)(3.1)(3.1) and 3. (3.1)(3.1)(2)
You check both of them:
1. 3*3-(-8)/4=9-(-2)=9+2=11 it's true
2. 3*4-4/4=12-1=11 true
so both of them are solutions
