To find the area of a triangle with the given sides a, b and c we use an expression,
Area = 
Where, 
By applying this formula area of the given triangle is 4.8 m².
Side lengths of the triangle are 2m, 4.8m and 5.2m
Therefore, 

Now substitute these values in the formula,
Area = 
= 
= 4.8 m²
Therefore, area of the triangle with the given sides is 4.8 m².

Answer: 2/3x 3/5 = 6/15
Step-by-step explanation: the grid has 15 squares so shade in 6 of the 15 squares
10 is not a perfect square I believe
122° and angle 1 are alternate interior angles and hence they are equal.
m1 = 122°
122° + angle 2 = 180° [sum of co interior angles is 180°]
angle 2 = 180° - 122°
m2 = 58°
