Question

find the area of a trapezium whose parallel sides are 40 cm and 30 cm and the area is 350 cm^2

Answer 1

Correct Question :

Find the $<b>height</b>$ of a trapezium whose parallel sides are 40 cm and 30 cm and the area is 350 cm².

$<u>Answer</u>$:

$<b>Area = 1 / 2 × Sum of parallel sides × Height </b>$

350 = 1 / 2 × ( 40 + 30 ) × Height

350 = 1 / 2 × 70 × Height

Height = 5 × 2

$<b>Height = 10 cm</b>$

Answer 2

Answer-

Area - 1/2* Sum of parallel sides*height

350 - 1/2 * (40+30) * height

350 - 1/2 * 70 * height

Height - 5*2

Height- 10 cm
