Question

(ii) The length of a side of a square of area (a) sqrt(4/49) 4 49 sq.cm. is (b) 2 7 cm. (c) 2 cm. (d) 7cm.​

Answer 1

Answer:

(b) 2/7

Step-by-step explanation:

Area = a^2

if the area of the square =4/49 then it is = a^2

4/49=a^2

take the square to the other side

so, root (4 / 49)=a                           (root 4 = 2 , root 49 = 7)

     2/7 =a
