Find the area of a triangle having base is 18cm and height is 12cm.

Step: 1

Given height(h) = 12cm

base of a triangle(b) = 18cm

Therefore,Area of a triangle = \$1/2 \times b \times h\$

= stem:[(18\times12)/12]

= stem:[\cancel(216)^(108)/ (\cancel2)]

Area of triangle  = 108  sq.cm

Explanation:

If the height of a triangle is 12cm and the base is 18cm, the area of the triangle is 108sq.cm as calculated using the formula: \$1/2 \times b \times h\$.
