Question

A Triangular Park has sides 120 m, 18 m and its perimeter is 250 m find the area of the field and length of the altitude on the longest side

Answer 1

Perimeter of triangle = 1/2(S1+S2+S3)
250=(120+18+S3)
250=138+(S3)
250-137=(S3)
113=S3

Area=(1/2)*h*b
Area=1/2 * 120 * 18
Area=1080 m square
