Answer : The area of wall = 30 foot²
Explanation:
Length of concrete wall = [tex]2\frac{1}{2}[/tex] foot
Breadth of concrete wall = 12 foot
Since, area means product of dimensions so we use the formula mentioned below:
Area of the concrete wall = length× breadth
[tex]2\frac{1}{2}\times 12\\=\frac{5}{2}\times12\\=\frac{60}{2}\\=30 \text{squared foot}[/tex]
So, the area of wall = 30 foot²
