Answer:
C
Step-by-step explanation:
P= side 1+ side 2 + side 3
40-(17+8)=15
15x8/2=60
Area of triangle, who has perimeter of 40 centimeters is 60 cm².
Area of a Triangle = A = ½ (b × h) square units
where b and h are the base and height of the triangle, respectively.
Given: Perimeter= 40cm
Now, 17+8+side=40
side= 40-25
side= 15 cm
Now, Area of triangle,
=1/2*b*h
= 0.5*15*8
= 60 cm²
Hence, Area of triangle= 60 cm².
