Question

∆XYZ ~ ∆DEF ,AC(∆XYZ):A(∆DEF) =16:25 then XY:DE=​

Answer 1

X Y = / DE = 4 / 5

Please mark me as a brainlist .

Answer 2

Answer:

4:5 is answer

Step-by-step explanation:

Let XY be b1 and DE be b2

A(XYZ:A(DEF)=b1^2:b2^2

by inverse of theorem of area of similar triangle

16:25=b1^2:b2^2. by taking square root

4:5=b1:b2

there fore XY:DE =4:5
