To find the width of the rectangular slab of concrete with a perimeter of 24 meters, and knowing that its length is 2 meters longer than its width, we can set up an equation.
Let w represent the width of the slab, then the length will be w + 2 meters. Since the perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width, we can express this as:
24 = 2(w + 2) + 2w.
Simplifying, we get:
24 = 2w + 4 + 2w.
Combining like terms gives us:
24 = 4w + 4,
and isolating w , we subtract 4 from both sides:
20 = 4w,
which gives us:
w = 5 meters.
Therefore, the width of the slab is 5 meters.
The width of the rectangular slab is 5 meters. The length is therefore 7 meters, as it is 2 meters longer than the width. This is calculated using the perimeter formula for rectangles.
