Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²

3. Zero Property
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
The diagonals of a parallelogram bisect each other.
The diagonals are PN and MO. The point A divides PN into 2 equal segments as well as MO into 2 equal segments.
Since AO = 6, MA should also be equal. Hence, MA (or AM) = 6.
The correct answer is AM = 6
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
= 
[2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
= 
[1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
