Answer 2

Answer:

Q 10. 12.25. Q11. l= 52 , b= 25

Step-by-step explanation:

Q10. By trails and error method : Answer is 12.25

see 12.25 - 12 = 0.25 And 1/2 of 0.25 is 0.125 (which is 1/8).

Q11. perimeter of rectangle = 2(l+b).

154. =. 2(l+b).............. (1)

154. =. 2((2b+2)+b).

77. =. 3b + 2.

=> 75. =. 3b.

=>. 25 = b.

From. (1). 52. =. l
