A rectangle has an area of #235.2m^2#. One of the sides is 2.8m in length. How do you work out the perimeter of the rectangle?

undefined To find the perimeter of the rectangle, you need to know the length of both sides. Since you know the area and one side length, you can use the formula for the area of a rectangle to find the length of the other side. Then, you can use the formula for the perimeter of a rectangle to calculate it. Here's the step-by-step process:

1. Find the length of the other side:
   Area = length × width
   235.2 m² = 2.8 m × width
   width = 235.2 m² / 2.8 m
   width ≈ 84 m

2. Calculate the perimeter:
   Perimeter = 2 × (length + width)
   Perimeter = 2 × (2.8 m + 84 m)
   Perimeter ≈ 2 × (86.8 m)
   Perimeter ≈ 173.6 m

Therefore, the perimeter of the rectangle is approximately 173.6 meters.

Kennedy Adams · Answer

#Perimeter=173.6#

Given that the rectangle's area is determined by:

#Area=side_1*side_2#

The equation can be solved by you:

#235.2=2.8*side_2#

You can multiply the perimeter by two after adding up the sides:

#Perimeter=(side_1+side_2)*2#

that's

#(2.8+84)*2=173.6#
