Find the height of a trapezium in which parallel sides are 25 cm 77 cm and non-parallel sides and 26 cm and 60 cm.
Answers
Answer:
CF = DF - CD
= ( 77 - 60 ) cm
= 17cm
For triangle BCF
Perimeter of the Traingle angled Traingle BCF = BC + BF + CF.
= (25+ 16+ 17)cm
=68cm.
Semiperimeter of the Traingle (s) = P upon 2 =
68
__ = 34 cm.

By heron formula is given in picture and continue is done here⬇
let h cm be the length of the perpendicular to CF.
