c)9/4 cm d) 11/4cm
​

Answer 1

Answer:

T =2

Step-by-step explanation:

15/4cm

Answer 2

16. Solve

Q. 3(t - 3) =5(2t + 1)

=> 3t - 9 = 10t + 5

=> 3t - 10t = 5 + 9

=> 7t = 14

=> t = 7/14

=> t = 2

ANs: t = 2

17.

Solve:

Let the length be l

Given width is w=2(3/4) = 11/4 cm

Then by perimeter formula we have

13=2(i+w)

=> l+11/4=13/2

=>l=13/2-11/4

=> l=15/4 cm

=>l=3(3/4) cm in mixed fraction form
