Question

The width of a rectangular path is 8 m. If the perimeter is 40m, what is the length of the path?

Answer 1

Perimeter of a rectangle= 2× (l+b) 2 × (x + 8) =40 2x + 16= 40 2x = 40-16 2x = 24 X = 24/2 X = 12 The length of the path = 12m

Answer 2

perimeter = 2[l+b], 40= 2[8+l],40=16+2l, 40-16=2l,24=2l,24/2=l,12=l
12 is the length
