The perimeter is 320. Just multiply 80 times 4
I am prertty sure it is the third opption. if not then I think you are right about the one you already chose. Super sorry if wrong
Answer:
2,457 mm^2
Step-by-step explanation:
The dimensions of each of the triangles in terms of their bases and heights will be;
26 mm by 27 mm
Mathematically, the area of one of the triangles will be ;
1/2 * base * height
= 1/2 * 26 * 27 = 351 mm^2
So the area of the heptagon is the sum of the areas of all of the triangles
mathematically, that would be;
351 * 7 = 2,457 mm^2
To find the answer to this, first, multiply the denominator by the whole number. So 3 times 4.
12+1/4
Next, add together the numerator to the value and put that number as the numerator.
Final Answer: 13/4
