Answer:
146.72 cm
Step-by-step explanation:
The area of a trapezium is computed with the following formula:
Area = 1 /2 × Sum of parallel sides × Distance between them
In triangle ADE
AD²=AE²+DE² (by Pythagoras theorem)
10²=4²+DE²
DE²=100-16
DE²=84
DE=9.165 cm
IN trapezium ABCD
Area = 1 /2 × Sum of parallel sides × Distance between them
Area = 1/2 ×(12+20)× 9.17
Area =1/2 × 32 ×9.17
Area =16× 9.17
Area =146.72 cm
