The width of a rectangle is fixed at 17cm. What length will make the perimeter greater than 94cm?
P = 2w + 2L
2*17 + 2L > 94
34 + 2L > 94
2L > 60
L > 30
length > 30 cm
Thank you.
an animal weight 73 pounds at birth and gain 2 pounds per day for the first few weeks determine those days for which the animals weight is more than 121 pounds. the animals weight is more than 121 pounds when the animal is more tha day ols
To find the length that will make the perimeter greater than 94cm, we need to use the formula for the perimeter of a rectangle, which is given by:
Perimeter = 2 * (Length + Width)
In this case, the width is fixed at 17cm. Therefore, the formula can be simplified to:
Perimeter = 2 * (Length + 17)
We want the perimeter to be greater than 94cm. So we can set up an inequality:
2 * (Length + 17) > 94
To solve this inequality for Length, we can start by dividing both sides by 2:
Length + 17 > 47
Next, we subtract 17 from both sides of the inequality:
Length > 47 - 17
Simplifying further:
Length > 30
Therefore, any length greater than 30cm will make the perimeter of the rectangle greater than 94cm.
