Question

Bases 12dm and 20 dm, altitude 10 dm find the area of trapezium

Answer 1

Answer:

Step-by-step explanation:

As we know that the formula for finding area of trapezium is:1\2×(a+b)×h

So here,

a=12

b=20

Altitude=10

So,

1/2(12+20)10 dm^2

=5(12+20) dm^2

=5×32 dm^2

=160 dm^2

Therefore, area of the trapezium is 160 dm^2
