a number expressed in standard form is
a × 
: 1 ≤ a < 10 and n is an integer
given
(7.5 × 
)(2 × 10³)
= 7.5 × 2 × 
= 15 × 
= 1.5 × 
×

Answer: 4 square inches</h3>
Explanation:
Square the linear scale factor to get 5^2 = 25

We take this idea in reverse to find the old area
old area = (new area)/25
old area = (100 sq inches)/25
old area = 4 square inches
