A rectangle is 3 times as wide as it is long if x=10 what's the perimeter

80 units if the length is equal to x (it is unspecified)

Step-by-step explanation:

Assuming that the length is equal to x, then we know that the length is 10 units long because x = 10.

Since the width is 3 times longer than the length, we can also find that the width is 30 units long because 3 x 10 = 30.

Now, we can use the perimeter formula to find the perimeter of the rectangle.

The perimeter formula is P = 2 ( L + W ), with L being length and W being width.

Let's just substitute the numbers to find perimeter.

P = 2 ( 10 + 30 )

P = 2 ( 40 )

P = 80

So, the perimeter is 80 units.
