Step-by-step explanation:
Build a rectangle 12 cm high and 5 cm wide (Paint it). Then a) Find the perimeter of the rectangle. B) Find the area of the rectangle. Aiuda porfis.
Length of the rectangle is 12 cm
Breadth of the rectangle is 5 cm
Perimeter is the sum of all sides. For rectangle it is given by :
P = 2(l+b)
⇒ P=2(12+5)
P = 34 cm
Area of a rectangle is equal to the product of its length and breadth.
So,
A = lb
A = 12 cm × 5 cm
⇒A = 60 cm²
Hence, perimeter is 34 cm and area of rectangle is 60 cm².

Step-by-step explanation:
Answer: 
Step-by-step explanation:
Since, Here the smaller number = 2n - 1
Since, Numbers are consecutive.
Therefore, remaining numbers are 2n - 1 + 2 , 2n - 1 + 2 + 2
= 2n +1, 2n +3
Thus, the sum of these all numbers = 2n - 1 + 2n + 1 + 2n +3
= 
( By equating the like terms)
Answer:
23 starfish, 7 octopi
Step-by-step explanation:
x=starfish
y=octopi
x+y=30
5x+8y=171
-5(x+y=30)
5x+8y=171
-5x-5y=-150
5x+8y=171
3y= 21
y=7
x+7=30
x=23
23 starfish, 7 octopi
