Answer:
(a) The area of a square with side 9 cm is 81 cm².
(b) The area of a square with side 3.5 cm is 12.25 cm².
Step-by-step explanation:
The question is:
Find the area of a square with the side of a) 9 cm b) 3 Whole and 1 half cm Please help I need it urgently !!!
Solution:
The area of a square is given by:
[tex]Area=a^{2}[/tex]
Here,
a = length of the side
(a)
The side of a square is, a = 9 cm.
Compute the area of this square as follows:
[tex]Area=a^{2}[/tex]
[tex]=9^{2}\\=9\times 9\\=81\ \text{cm}^{2}[/tex]
Thus, the area of a square with side 9 cm is 81 cm².
(b)
The side of a square is, a = 3.5 cm.
Compute the area of this square as follows:
[tex]Area=a^{2}[/tex]
[tex]=3.5^{2}\\=3.5\times 3.5\\=12.25\ \text{cm}^{2}[/tex]
Thus, the area of a square with side 3.5 cm is 12.25 cm².
