Question

Find the area of trapezium, whose parallel sides are 20cm and 10cm. Its non-
parallel sides are both equal, each being 13 cm,​

Answer 1

Step-by-step explanation:

A= a+b/2 h

this is the formula

Answer 2

Answer:

area of trapezium = 180 cm^2

Step-by-step explanation:

base = 20-10/2=10/2=5cm each. height ^2 = hapoteneous^2 - base^2 ; h^2 = 13^2-5^2 ; h^2 = 169 - 25 ; h^2 = 144 ; h √144 ; h = 12 cm. area of trapezium = 1/2 × (20+10) × 12 = 1/2 × 30 ×12 = 30 ×6 = 180 cm ^2. I hope it help you
