Question

The perimeter of trepezium is 104 m, its non- parallel sides are 18 m and 22m, and its altitude is 16m. Find the area of trepezium

Answer 1

The perimeter of trepezium=104m

The perimeter of trepezium=(sum of ║ sides)+(sum of ∦ sides)

104=(sum of ║ sides)+(18+22)

sum of ║ sides=104-40

sum of ║ sides=64

Area of trepezium=1/2×(sum of ║ sides)×(altitude)

Area of trepezium=1/2×64×16

Area of trepezium=512m²
