Question

find the area of the triangle given below and type your result in the empty box. 15 cm 12 cm 19 cm answer: cm²

Explanation:

Step1: Identify triangle type

It's a right - triangle, so legs are base and height. Let base $b = 15$ cm, height $h = 12$ cm.

Step2: Apply area formula

Area of triangle $A=\frac{1}{2}\times b\times h$. Substitute $b = 15$, $h = 12$: $A=\frac{1}{2}\times15\times12$.

Step3: Calculate the value

$\frac{1}{2}\times15\times12 = 15\times6=90$.

Answer:

90
