Find the missing value:
| Base | Height | Area of triangle |
| 15 cm | ______ | 87 cm2 |
उत्तर
| Base | Height | Area of triangle |
| 15 cm | 11.6 | 87 cm2 |
Explanation:
Area of Triangle = `1/2 xx "Base" xx "Height"`
b = 15 cm
h = ?
Area = `1/2 xx b xx h` = 87 cm2
`1/2 xx 15 xx h` = 87 cm2
h = `(87xx 2)/15`
h = 11.6 cm
Therefore, the height of triangle is 11.6 cm.
