Answer:
? ≈ 4.4 in
Explanation:
the area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
here b = 4.2 , h = ? and A = 9.2 , then
× 4.2 × ? = 9.2 ( multiply both sides by 2 to clear the fraction )
4.2? = 18.4 ( divide both sides by 4.2 )
? =
≈ 4.4 in ( to the nearest tenth )
