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.
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.
