Question

Find the base of the triangle when the area is 94.5

Answer 1

Base = 10.5 cm

Explanation:

GIVEN :-

• Height of the triangle = 18 cm
• Area of the triangle = 94.5 cm²

TO FIND :-

• The base of the triangle

GENRAL FORMULAE TO BE USED IN THIS QUESTION :-

For a triangle with height 'h' & base 'b' , its area =
`(1)/(2) * b * h`

SOLUTION :-

`Area = (1)/(2) * Base * Height`

`=> 94.5 = (18b)/(2)`

• Multiply both the sides by 2

`=> (18b)/(2) * 2 = 94.5 * 2`

`=> 18b = 189`

`=> b = (189)/(18) = 10.5`
