What is the answer to this question

(A) 2:1

Step-by-step explanation:

If BC = 2, CD = 3, AE = 3, EC = 4, then what is the ratio of the area of ECD to the area of AEB?

Area of ECD = 1/2*3x*4x= 6x^2

(since ratio value is unknown, we make it x)

Area of ACB = 1/2*2x*7x=7x^2

Area of BEC = 1/2*2x*4x=4x^2

So, AEB = ACB - BEC

= (7-4)x^2= 3x^2

ECD : AEB= 6x^2:3x^2 = 2:1

Ans = 2:1

unless if u could do my questions, if not i wouldn't want to

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
