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:
y=-3.667
x=
Step-by-step explanation:
-4(10y-59)+10y=86
30y+196=86
30y=-110
y=-3.667
9 + 9 = 18
42 - 18 = 24
24 / 2 = 12
the length is 12 inches
