Answer:
Part a-
area= 35
perimeter= 31
part b-
area= 25
perimeter= 18
Step-by-step explanation:
to find the area of a triangle you multiply 1/2Bh
so for part A:
A= [tex]\frac{1}{2}[/tex] (10)(7) (honestly, you can just input the whole equation into the calculator)
A=(5)(7)
A= 35
and for part B:
A= [tex]\frac{1}{2}[/tex](8.34)(6)
A= (4.17)(6)
A=25.02 (or just 25)
THEN, to find the perimeter you add up all of the sides
so for part A:
P= 14 + 10 + 7 = 31
and for part B:
P= 4 [tex]\frac{1}{3}[/tex] + 8 [tex]\frac{1}{3}[/tex] + 5 [tex]\frac{1}{3}[/tex] = 17 [tex]\frac{3}{3}[/tex] or 18
I hope this helps :)
