Answer:
1/25 of initial area
Step-by-step explanation:
Since the triangle has been reduced by 1/5, all dimensions also reduce by 1/5
If it was a right angle triangle where area is given by 0.5bh
The original area is 0.5bh
When base is reduced by 1/5, the new base is b/5. Similarly, the new height will be h/5
The new area will be 0.5b/5*h/5=0.5bh/25
Clearly, the new area has been reduced by 1/25 compared to the original area
