Answer:
A = 1189 cm².
Explanation:
Since a computer monitor is shaped like a rectangle, we know that the formula for the perimeter is [tex]P= 2l + 2w[/tex].
If we know the width, we can solve for the length:
140 = 2w + 2(29)
140 = 2w + 58
82 = 2w
w = 41.
To find the area, we use the formula [tex]A= l * w[/tex].
A = 41 ×29
A = 1189 cm².
