Answer:
502m
Step-by-step explanation:
let x and y represent the length and breadth of rectangular meadow respectively.
Given,
Perimeter of the meadow =1004m
or,2(l+b)=1004m
or2(x+y)=1004m
orx+y=1004m/2
or,x+y=502m
i.e sum of length and breadth
False, vertical angles are not next to each other but opposite of each other
Combine the two sets to form one giant set. If needed, toss out any duplicate values.
So,
A U B = {4,7,10,13,17, 3,5,7,9}
Toss out the duplicate item "7" and sort the values to get
A U B = {3,4,5,7,9,10,13,17}
