529.72......................
Subtract the original from the new to find the difference:
148 - 74 = 74
Now divide the new by the difference:
148 / 74 = 2
Multiply that by 100 to get the percentage:
2 x 100 = 200%
It was a 200% increase.
Answer:
0.65 square inch
Step-by-step explanation:
Each triangle has an area given by ...
A = 1/2bh = 1/2·(0.5 in)(0.4 in) = 0.10 in²
The square base has an area given by ...
A = s² = (0.5 in)² = 0.25 in²
The total area is that of the square base and 4 triangles:
S = 0.25 in² + 4×0.10 in² = 0.65 in²
