Question

The parallel sides of a trapezium are 20 cm and 13 cm It's non parallel sides are 10 cm each find the area of trapezium

Answer 1

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

$= \frac{1}{2} \times 20 + 13 \times 10 \\ \\ = \frac{1}{2} \times 33 \times 10 \\ \\ = \frac{3 3 \times 10}{2} \\ \\ = 33 \times 5 \\ \\ = 165$

Area of trapezium is 165 cm^2

Answer 2

Answer:

215cm^2

Step-by-step explanation:

area of trapezium =1/2×(sum of parallel sides)×hieght

=1/2×(20+13)×10

= 1/2×43×10

= 43×5

=215 cm^2
