Total length of fabric is: 3 + 3 + 5 = 11 feets
Answer:
To find the perimeter of this triangle, we add up all the sides together.
(8 · √3) + (8 · √3) + √384
But before we add them, let's simplify them.
(8 · 1.7) + (8 · 1.7) + 19.6
13.6 + 13.6 + 19.6
27.2 + 19.6
= <u>46.8</u>, is the perimeter of this triangle.
Now to find the area, we use the formula:
(formula for area of a triangle)
A = BH · 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.
<u><em>What we know:</em></u>
- Base = 8 · √3 which equals <u>13.6</u>.
- Height = 8 · √3 which equals <u>13.6</u>.
Plug in the values into our formula:-
A = BH · 1/2
A = 13.6(13.6) · 1/2
A = 184.96 · 1/2
A = 184.96/2
A = <u>92.48</u>, is the area for this triangle.
Answer:
The lines that make this up are y = 5, x = 4 and y = x so the answer is y ≤ 5, x ≥ 4 and y ≥ x.
