if the difference of the semi perimeter and the sides of triangle are 60m, 13m and 10m and the area of the triangle is 1344 m^2

Question

Find the height of the triangle corresponding to the smallest sides of triangle

Very very urgent

Answer 1

Heron's formula says that the area
A = √(s(s-a)(s-b)(s-c))
So it appears that the smallest side is 10, so
10h/2 = 1344

Answer 2

So what's the use of this line

difference of the semi perimeter and the sides of triangle are 60m, 13m and 10m
