Answer:
use the formula of trapezium

Answer:
Parallel sides of trapezium = 25cm, 30cm
⇒ CD = 15cm AB = 30cm
and, AD = 15cm
Area of trapezium = sum of parallel sides X height/2
For this we need to calculate the height:-
Now draw a perpendicular from D to AB and a line parallel to BC which meets AB at P
∴ PB becomes equal to CD
⇒ PB = CD = 25cm
⇒ AP = 30 - 25 = 10cm
Now in ΔAPD
H² = B² + P²
15² = 10² + h²
225 - 100 = h²
√25 = h
⇒ h = 5cm
⇒ Area of trapezium = 25+30 X 5/2
= 55X5/2
= 275/2 = 137.5cm²
Step-by-step explanation:
Hope it helps you buddy :)
