Question

The parallel sides of a trapezium are 12 cm and 36cm. If the perpendicular distance for the the parallel sides is 15cm, then find its area

Answer 1

Step-by-step explanation:

Area of a trapezium=

1

2

×(Sum of parallel sides)×(Distance between them)

={

×44×15) cm2=(22×15) cm2=330 cm2

Hence, the area of the trapezium is 330 cm2.

Answer 2

Answer:

360$cm^{2}$

Step-by-step explanation:

F(x) for area of a trapezium is (sum of parallel sides)*(height)

=(12+36)(15)

=48*15

=360$cm^{2}$

For full proof, see attachment.

Hope this helps. Good day to you.
