Question

The areas of two similar triangles are in respectively 9 cm2 and 16 cm2. The ratio of their corresponding sides is
(a) 2 : 3                                   (b) 3 : 4                   (c) 4 : 3                          (d) 4 : 5​

Answer 1

Answer:

b) 3:4

Step-by-step explanation:

root over 9:16 is 3:4

Answer 2

Answer:

3:4

Step-by-step explanation:

By formula,

Area of ABC/Area of PQR = Length of side A ^2/Length of side B^2

9/16 = x/y

On squaring both sides we get,

3/4 = x/y

On equating we get

x = 3 and y = 4
