Step-by-step explanation:
The area of a triangle is calculated by multiplying the base by the height and then dividing the answer by 2.
A = bh/2
We can use this as a formula to find the base by substituting in the given values:
64 = 16b/2
Multiplying both sides by 2 will get rid of the fraction and isolate the b term:
64x2 = 16b/2 x2
128 = 16b
Finally we divide both sides by 16:
128/16 = 16b/16
8=b
The base is 8m.
Hope this helped!
