The design and the photocopy are congruent
the length (DA + BC) = 47 - 15 - 17 = 47 - 32 = 15

Now using the Fact that DA:BC = 1:2 you can find the length of DA and BC

EH is equal to length of AD.

welshfella · Answer

can you split up 15 into 2 numbers whose ratio is 1:2?

welshfella · Answer

one number will be 15 *    1/(1+2)  and the other  =   15* 2 (1+2)
