Answer:
As you probably know the perimeter of a rectangle is given by the formula 2l + 2w where the length and width are represented by the letters l and w .
In our case,
l = w + 5 ( since the problem states that the length is 5 more than the width)
70 = 2 (w+5) + 2w
70 = 2w + 10 + 2w
4w = 60
w = 15
l = 20
Our length is going to be 20 ft and our width 15 ft.
Explanation:
The perimeter is the sum of the two lengths and the two widths.
So if we let L = the length and W = the width, 2L + 2W = 70
If the length is 5 feet more than the width, then L = W + 5
Substitute W + 5 for L in the first equation--> 2(W + 5) + 2W = 70
2W + 10 + 2W = 70
4W + 10 = 70
4W = 60
W = 15
So L = 20
Plug these numbers back in to the question to make sure that they work.
Have fun.

The answer is shading.
The key characteristic that is featured in African rock paintings but is not present in European and Australian rock paintings is shading. The rock paintings of Africa feature complex and exquisitely minute details of shading.
Rock painting is one of the oldest art forms of Africa that is practised even today. The paintings depict human figures, animals and figures with both human and animal characteristics. Polychrome shading is very common in rock painting. This shading gives the painted objects a three-dimensional look and feel.
