Lets say that the length of a rectangle is 12 cm and the width is 5 cm, you would add 12+12+5+5 (as in the length on both length sides and the width on both sides) so the perimeter of this rectangle is: 34 cm
Answer:
21
Step-by-step explanation:
Answer:
37
Step-by-step explanation:
Split the arrow into a rectangle and triangle. The area of the rectangle is 7x4=28. The area of the triangle is 6*3/2=9. 28+9=37
Answer:
Area = 702.9 or 703
Step-by-step explanation:
By Pythagoras the. first, we need to find the base!
(H)2 = (P)2 + (B)2
(82)2 = (18)2 + b2
6724 = 324 + b2
b2 = 6724-324
b2 = 6100
b = √6100
b = 78.1
note - they all are in square
Now, area of the triangle:-
1/2 * b * h
1/2 * 78.1 * 18
= 702.9
Hope it helps!
Answer:
(2n + 1)[(2n + 1) � 1]
(2n + 1)(2n + 1 � 1)
(2n + 1)(2n), or 2n(2n + 1)
2n is an EVEN NUMBER, and adding 1 to an even number creates an ODD number
Therefore, 2n(2n+1)=EVEN NUMBER ODD NUMBER=EVEN NUMBER
