Answer:
60
Step-by-step explanation:
Perimeter = 40 cm
Sum of two sides = 18 cm + 12 cm = 30 cm
Therefore, third side = 40 cm - 30 cm = 10 cm
Longest side = 18 cm
Hence, area of triangle = 1/2 x 12 x 10 = 60

Answer: 60 cm^{2}
Step-by-step explanation:
40 =18+12+x
40=30+x
40-30=10
10=x
The three sides of the triangle are 18,12, and 10
Area of a triangle =1/2xbxh
=1/2x10x12
=60
