Question

Find the area of the trapezium in which parallel sides are of lengths 5cm add 11cm whereas non parallel sides are of lengths 4cm and 6cm.

Answer 1

Given,
length of parallel side= (5+11) cm
length of non-parallel side =4 cm and 6 cm

so, height =3^(1/2×3)

now,
area of trapezium =1/2(sum of the parallel side) × height
=(1/2(16) ×(3^(1/2×3) cm^2
= (24×(3^1/2×3) cm^2

Answer 2

341.3 cm is the area of the trapezium
