Area of trapezium ABCD.

ABCD is a trapezium in which AB is parallel to CD. Let M be the midpoint of CD. Consider the following statements : 1. Area of triangle ABM - Area of triangle ADM is always equal to area of triangle BCM, if AB = CD 2. Half of area of triangle ABM is equal to one-eighth of area of trapezium ABCD, if AB = CD. Which of the above statements is/are correct?

ABCD is an isosceles trapezium with vec AB=2hat i+10hat j+11hat k and vec AD=-hat i+2hat j+11hat k and AB such that AE:EB=3:2. If A_(1) and A_(2) are areas of trapezium ABCD and /_CDE respectively then A_(1):A_(2) equal to

Find the area of a trapezium ABCD in which AB || DC, AB = 26cm, BC = 25cm, CD = 40cm and DA = 25cm.

Find the area of a trapezium ABCD in which AB||DC,AB=77 cm ,BC = 25 cm, CD = 60 cm and DA = 26 cm .

The parallel sides of a trapezium ABCD are 16 cm. AF and BE and are the perpendiculars drawn to bar(DC) . Find the total area of the triangle ADF and BCE (in cm^(2) ).

In the figure,the semicirce centered at O has a diam.eter 6cm. The chord BC is parallel to AD and BC=(1)/(2)AD. The area of the trapezium ABCD in cm^(2), is :

ABCD is a trapezium with AD and BC parallel sides. E is a point on BC. The ratio of the area trapezium ABCD to that of triangle AED is- ABCD एक AD और BC समांतर भुजाओं वाला समलंब चतुर्भुज है। E,BC पर एक बिंदु है। square ABCD और triangle AED के क्षेत्रफल का अनुपात क्या होगा?

In a trapezium ABCD, AB and DC are parallel sides and angle ADC = 90^@ ,if AB = 15 cm, CD = 40 cm and diagonal AC = 41 cm. Then the area of the trapezium ABCD is एक समलंब में AB और DC समांतर किनारे है और angle ADC = 90^@ है । यदि AB = 15 से.मी., CD = 40 से.मी. और विकर्ण AC = 41 से.मी. है, तो उस समलंब ABCD का क्षेत्रफल बताइए ।
