Question

The area of a trapezium is 234 cm2 . The lenght of its parallel side are 20 cm and 32 cm. Find the its altitude

Answer 1

Answer: 9cm

Step-by-step explanation:

Area of trapezium =altitude×sum of parallel sides /2

234=x (20+32)/2

468=52x

X=9

Hope it helps!

Answer 2

Base₁ = 20  cm

Base₂ = 32  cm

Area = 234  cm²

$Height = 2\ \frac{Area }{Base_1 + Base_2}$

$Height = 2\ \frac{234}{30 + 32}$

$Height = 2\ (\frac{234}{52})\\\\\\Height = 2\ (4.5)\\\\\\Height = 9\ cm$
