a rectangular mural measures 1 meter by 3 meters. Rebekah creates a new mural that is 0.5 meters longer. what is the perimeter of Rebekah's new mural?

old perimeter = 2(1+3) = 8

since two parallel sides are each 0.5m longer, it adds 1.0m to the perimeter.
2(1.5+3) = 9.0 m

It is right

I agree it is right

Well, Rebekah's new mural is 0.5 meters longer than the original, so its length would be 1 meter + 0.5 meters = 1.5 meters. The width remains the same at 3 meters.

To find the perimeter of the mural, you add up all the sides. So, the perimeter is (1.5 meters + 3 meters) + (1.5 meters + 3 meters) = 9 meters.

So, the perimeter of Rebekah's new mural is 9 meters. That's a lot of ground to cover if you're a tiny ant!

it is right i searched it up

To find the perimeter of Rebekah's new mural, we need to add up the lengths of all four sides of the rectangular mural.

Given:
Length of the rectangular mural = 1 meter
Width of the rectangular mural = 3 meters

Since the new mural is 0.5 meters longer, we can add 0.5 to the length of the mural.
New length of the mural = 1 + 0.5 = 1.5 meters

We can now calculate the perimeter of the new mural by adding up all four sides:
Perimeter = Length + Width + Length + Width

Plugging in the values:
Perimeter = 1.5 + 3 + 1.5 + 3

Simplifying the expression:
Perimeter = 6 + 4.5

Calculating the sum:
Perimeter = 10.5 meters

Therefore, the perimeter of Rebekah's new mural is 10.5 meters.
