length of the two parrell sides of a trapazium are 8.5cm and11.5cm respectively and it's height is 4.2cm find its area
Answers
Answer:
42 cm²
Step-by-step explanation:
length of first parallel Side (a) = 8.5cm
length of second parallel Side (b) = 11.5cm
height (h) = 4.2cm
area of trapezium = ½ x ( a+ b ) x h
= ½ x ( 8.5 cm + 11.5 cm ) x 4.2cm
= ½ x 20 cm x 4.2cm
= 10cm x 4.2 cm
= 42cm²
Answer:
The area of trapezium=42cm^2
Step-by-step explanation:
Length of the two parallel sides= 8.5cm and 11.5cm
Sum of parallel sides=8.5+11.5= 20cm
Height= 4.2cm
Area of trapezium=½ x (sum of parallel sides) x h
=1/2 x (20) x 4.2
=10 x 4.2
= 42cm^2
