Answer:
3 inches
Explanation:
Formula for area of a triangle:
A = 1/2BH
Where "B" represents the base and "H" represents the height.
Plug in the given values and solve for "H" (height), but first, make the measurements improper fractions to solve more easier:
5 1/10 become 51/10(area) square inches
3 2/5 becomes 17/5(base) square inches
A = 1/2BH
Substitute:
51/10 = 1/2(17/5)H
51/10 = 17/10H
Divide both sides by 17/10 by multiplying it's reciprocal to both sides:
51/10(10/17) = H
H = 510/170 which simplifies to 3.
