Question

calculate the area of a trapezium In cm^2,length of whose parallel side ( represented by a and b and distance between them height are a=4dm,b=8,h=1m a=14cm,b=18cm,h=15cm a=8.5cm,b=3.4,h=6cm​

Answer 1

Step-by-step explanation:

area of trapezium is 1/2 × ( sum of parallel sides ) × height

= 1/2 ×(a+b) × h

Answer 2

Step-by-step explanation:

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

= 1÷2 × ( 8+4) 1

= 1÷2 × 12

= 6m^2

area of other trapezium = 1÷2 × ( 14 + 18 ) 15

= 240 cm ^2

area of last trapezium = 1÷2 × ( 8.5 + 3.4 ) 6

= 35.7 cm ^2
