I think it is 66 not for sure tho thats my answer <span />
A is definitely the answer.
When you multiply two numbers which have the same sign the answer is positive. Therefore multiply eight and three to get 24 and the answer is positive; therefor the answers 24.
All you do is subtract the two numbers
Answer:60
Step-by-step explanation:
a=13 b=13 c=10
Perimeter of =a+b+c
perimeter of =13+13+10
Perimeter of =36
S=36 ➗ 2
S=18
Area=√s(s-a)(s-b)(s-c)
Area=√18(18-13)(18-13)(18-10)
Area=√18(5)(5)(8)
Area=√(3600)
Area of =60
