Find the area of triangle ABC. Give your answer correct to 1 decimal place.

83.3 cm²

Step-by-step explanation:

First we should calculate the height of this triangle using the pythagorian theorem

Let h be the height of the triangle :

Let A be the area of the triangle :

   31.7 cm^2

Step-by-step explanation:

We can use the formula

A = 1/2 ab sin C  where a and b are two sides and C is the angle between them

C = 180 - 72 - 59 = 49

A = 1/2 ab sin C

   = 1/2 ( 7)(12) sin 49

     31.69780237

To 1 decimal place

   31.7 cm^2
