Question

Ratio of areas of two similar triangles is 144:441, then ratio
of their perimeter is
A) 14:41
B) 44:41
C) 7:4
D) 4:7​

Answer 1

144÷441

Step-by-step explanation:

answer is this something is wrong

Answer 2

Step-by-step explanation:

Suppose two similar triangles are ∆ABC and ∆DEF.

Then,

Area of ∆ABC/Area of ∆DEF= 144/441

=(12)^2/(21)^2= 12/21=4/7

Perimeter of ∆ABC/Perimeter of ∆DEF=4/7
