Height to the base

The triangle area is 35 cm ^ 2. The size of the base is 10 cm. Find the length of height to the base.

Result

v =  7 cm

Solution:

S=35 cm2 a=10 cm  S=av2  v=2⋅ S/a=2⋅ 35/10=7 cmS=35 \ \text{cm}^2 \ \\ a=10 \ \text{cm} \ \\ \ \\ S=\dfrac{ av }{ 2 } \ \\ \ \\ v=2 \cdot \ S/a=2 \cdot \ 35/10=7 \ \text{cm}
