Question

*Find the area of trapezium ABCD, shown in the figure.*

1️⃣ 85 cm²
2️⃣ 25 cm²
3️⃣ 42.5 cm²
4️⃣ 28.333 cm²​

Answer 1

Answer:

42.5 CM^2

Step-by-step explanation:

Area of trapezium:1/2(sum of parallel sides)*distance between them(height)

parallel sides are:

1. AB=7CM
2. DC=10CM

Height:

1. AD=5CM

BECAUSE

It is perpendicular to DC.

So,

1. Area=1/2(7+10)cm*5cm
2. =1/2*17cm*5cm [10+7=17]
3. =1/2*85cm^2 [17*5=85]
4. =85cm^2/2
5. Answer:42.5cm^2
