Answer:
64
Step-by-step explanation:
Substitute in the numeric values for the variables, and now you have
9(3+2(2)) +1. Simplify, and now you have 9(3+4) +1. Use pemdas to get 7 for the value in the parentheses, and then multiply 9 and 7 to get 63. Add 1 and 63 and now you have 64.
Step 1: Define
9(a + 2b) + c
a = 3
b = 2
c = 1
Step 2: Substitute and Evaluate
9(3 + 2(2)) + 1
9(3 + 4) + 1
9(7) + 1
63 + 1

The ratio of the length and the breadth of rectangle=2:1
Let length be 2x, then breadth = x
Now,
Length(l)=12 m
or,2x=12m
or,x=6m
x=breadth=6m
