Question

the length of a rectangular playing field is 5 metres longer than its width.If the perimeter of the field is 150 metres find its width

Answer 1

Step-by-step explanation:

let x be width

gn

length = (5+x ) metre

width = x metre

perimeter = 2(l+w) metre

150m = 2(5+x+x) m

150 = 2(5+2x)

150/2 = 5+2x

75-5 = 2x

70/2 = x

x = 35 m

width = 35m

length = 35+5 = 40

Answer 2

Answer:

35m

Step-by-step explanation

150 divide by 2 = 75

let the value of width be x

width    length     total

 x            x+5         75

x + x + 5 = 75

2x + 5 = 75

2x + 5 -5 = 75 - 5

2x = 70

2/2x = 70/2

x = 35
