Please Help Me With This Problem!!!!
Answer: The area is [tex]320m^2[/tex]
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
[tex]A=lw[/tex]
Where "l" is lenght and "w" is the width.
We know the width and the perimeter, then we can solve for the lenght from the following formula, which is used to calculate the perimeter of a rectangle:
[tex]P=2l+2w[/tex]
Then:
[tex]72m=2l+2(16m)\\72m-32m=2l\\\l=\frac{40}{2}\\\\l=20m[/tex]
Substituting values into the formula [tex]A=lw[/tex], we get that the area of the rectangle is:
[tex]A=(16m)(20m)[/tex]
[tex]A=320m^2[/tex]
Answer:
The area of rectangle = 320 m²
Step-by-step explanation:
Points to remember
Area of rectangle = lb
l - length and b - width
It is given that, perimeter of rectangle is 72 m. And width of rectangle = 16 m
To find the value of length
Perimeter = 2(l + b)
72 = 2(l + 16)
36 = l + 16
l = 36 - 16 = 20
To find the area of rectangle
Area = lb
= 20 * 16
= 320 m²
Therefore area of rectangle = 320 m²
