Here we are given the three sides of the triangle.
So we have Heron's formula to find its area.
Heron's formula is given by :

where A, B and C are sides of triangle and S is semi perimeter which is given by,

plugging values of A, B and C to find S

S=13.5
Now plugging values of A, B , C and S in Heron's formula

A=26.14 mm²
Answer: Area of triangle is 26.14 mm².
It doesn’t include the number it just stops there
£57.6 bc it is extremely cool and correct
B is the right answer because a is too short and c and d are too long
She would make about 17.35 because $850 divided by 49 is 17.3469388 rounded is 17.35
