ABCD is a trapezium with BC = 11 cm. 4D = 15 cm and BC parallel to 4D. The point E on AD is such that EC is parallel to AB The area of triangle ECD = 7 cm Find the area, in cm^2, of the trapezium ABCD.

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically

4932,9180,7625 are divisible by 9

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
