Draw four rectangles of different sizes each having a perimeter of 16 cm ( plz tell the formula so that I can find the numbers)
Answers
(1)16/2=8
(2)now find the number of ways u can add two numbers say x,y so that it results 8
i.e.,x+y=8
(3)»
1+7=8
2+6=8
3+5=8
4+4=8.
Four rectangles of different sizes each having perimeter of 16 cm:
- Perimeter of rectangle = 2(l + b)
l = length of rectangle
b = breadth of rectangle
- 2(l + b) = 16
l + b = 16/2 ⇒ l + b = 8 cm
- Hence, we can draw any number of rectangles whose length and breadth sum up to 8 cm.
- Case 1: l = 7 cm, b = 1 cm
Perimeter of rectangle = 2(1 + 7)
= 2(8)
= 16 cm
- Case 2: l = 6 cm, b = 2 cm
Perimeter of rectangle = 2(6 + 2)
= 2(8)
= 16 cm
- Case 3: l = 5 cm, b = 3 cm
Perimeter of rectangle = 2(5 + 3)
= 2(8)
= 16 cm
- Case 4: l = 5.5 cm, b = 2.5 cm
Perimeter of rectangle = 2(5.5 + 2.5)
= 2(8)
= 16 cm
