The sum of two sides of the garden =
Perimeter is the sum of all sides of a triangle.
Third side = Perimeter of triangular garden - sum of two sides of the garden
The expression represent the third side = .
Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18
Answer:
200.5 km
Step-by-step explanation:
So we can break up this irregular polygon into many smaller easier to calculate kind of polygons like rectangle, or triangles.
We can break up this figure into 4 smaller ones:
3 rectangles:
a) a 23 by 5 size
b) a 12 by 4 size
c) a 4 by 5 size
1 triangle
a) 7 by 5 size
You find the area and add them up to get 200.5 km^2
