Answer:
The length of the base is [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Since we know the formula to find the area of a triangle is [tex]A = \frac{1}{2} bh[/tex], we can plug in and solve for b. When we plug into the formula we get:
[tex]\frac{1}{2} (\frac{1}{5} )b[/tex] = [tex]\frac{3}{40}[/tex]
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:
[tex]\frac{1}{5}b = \frac{3}{20}[/tex]
Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:
[tex]b = \frac{3}{4}[/tex]
