The area of a triangular park is 240m. If two sides are 78,and 50m, find the length of the perpendicular on the side of length 50 m from the opposite vertex.Please answer

Answer»

Answer:

PERIMETER of triangular PARK = 240m

LENGTH of two SIDE are- 1) 78m

                                2) 50m

let 3rd side be          = X meter

78+50+x = perimeter of triangle

78+50+x = 240m

128+x     = 240m

x             = 240-128

x             = 112m

therefore, the length of third side is 112m .
