Answer:
a, b, and c can be formed a triangle
The area of the triangle is 13385.87 square units.
Step-by-step explanation:
<em>Let us revise an important fact in any triangle</em>
- The sum of the lengths of the two shortest side must be greater than the length of the longest side
The length of the sides are a = 240, b = 132, and c = 330
∵ The two shortest sides are a = 240 and b = 132
∵ a + b = 240 + 132 = 372
∵ The longest side is c = 330
∵ 372 > 330
∴ a + b > c
∴ a, b, and c can be formed a triangle
<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>
- Area =
, where a, b,c are the lengths of the sides of the triangle, and
∵ 
∴ 
∴ 
∴ 
The area of the triangle is 13385.87 square units.
Answer:
A

Answer:
71 M
Step-by-step explanation:
to find the perimeter you need to add up all the sides (length and width)
in this case they already gave you the perimeter: 306
and the length: 82
there are two sides that are the length so you need to do 82x2 which is 164
now you need to subtract 306-164=142
142 is the sum of the two width but its asking for only one side so 142 divided by 2 is 71
Pretty Sure it’s y=x+(-.8) haven’t done algebra in a bit. Sorry if wrong. :/
