Find the missing value:

Base Height Area of triangle
15 cm ______ 87 cm2
Advertisements

Solution

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` = 11.6 cm

Therefore, the height of triangle is 11.6 cm.

  Is there an error in this question or solution?
