The area of a triangle is 56 squared centimeters. give all possible sets of whole number dimensions for the base and height of the triangle

The formula for the area of a triangle is:
hb/2 
so if the area of a triangle is 56 you can say:
hb/2 = 56 ⇒ hb = 112 
now you can find the numbers of h and b:
they can be: 56 and 2 
they can be: 28 and 4 
they can be: 16 and 7 
they can be: 14 and 8 :))
i hope this is helpful
have a nice day 

The answer is 41.7 because 1.39 times 30 is 41.7
