Question

The parallel side of trapezium is 77 m and 6 cm and its non parallel sides are 26 m and 25 m find the area of trapezium

Answer 1

Parallel side of trapezium is 77m

and 6 cm and non-parallel sides are 26 m and 25 m.

Area of trapezium is?  

S = a+b+c/2

S = 25+26+17/2

S = 34 m

Area =root (s* (s-a)* (s-b)* (s-c))

Area = root (34* (8* 9* 17)

Area=204 m²

Area of triangle ADE=1/2 *b *h

204=1/2 * 17 *h

24= h

h= 24 m

The height of trapezium is 24m

Area=1/2* (a+b) *h

Area=1/2* (60+77) *24

Area=1644 cm²
