Question

find the height of a triangle whose area is 90a ssquare units and base is 18a units​

Answer 1

Answer:

Height of triangle is 10a

Step-by-step explanation:

We know that Area of triangle

$A = \frac{1}{2} (base \times height)$

Putting the values

$A = \frac{1}{2} (base \times height) \\ 90 {a}^{2} = \frac{1}{2} \times ( 18a \times h) \\ 180 {a}^{2} = 18a \times h \\ h = \frac{180 {a}^{2} }{18a } = 10a$

Height of triangle is 10a
