The length of the box is 4.6 meters and the width is 2.6 meters. The perimeter of the box can be found by adding up all four sides of the rectangle.
Perimeter of the box = 2(length) + 2(width)
= 2(4.6) + 2(2.6)
= 9.2 + 5.2
= 14.4 meters
Now, an addition is built that is 2.5 meters longer than the box. This means the length of the addition is 4.6 + 2.5 = 7.1 meters.
The width of the addition remains the same at 2.6 meters.
To find the new perimeter, we add up all four sides of the larger rectangle.
New perimeter = 2(new length) + 2(width)
= 2(7.1) + 2(2.6)
= 14.2 + 5.2
= 19.4 meters
Therefore, the new perimeter is 19.4 meters.
A box measures 4.6 meters by 2.6 meters a addition is built that is 2.5 meters longer what is the perimeter now
