Answer:
The base of traingle is 4cm.
Step-by-step explanation:
Given that the area of triangle is A = 1/2×b×h where b represents base and h is height. So you have to substitute the values into the expressions and solve it :
[tex]area = \frac{1}{2} \times b \times h[/tex]
[tex]let \: area = 12,h = 6[/tex]
[tex]12 = \frac{1}{2} \times b \times 6[/tex]
[tex]12 = 3 \times b[/tex]
[tex]12 \div 3 = b[/tex]
[tex]b = 4[/tex]
