Step-by-step explanation:

let w represent the width then length = w + 7

The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14

The perimeter is given as 54 m, thus

4w + 14 = 54 ( subtract 14 from both sides )

4w = 40 ( divide both sides by 4 )

w = 10

Thus

width of playground = w = 10 m

length of playground = w + 7 = 10 + 7 = 17 m

Answer:

17m × 10m

Step by step explanation:

Total edging = Perimeter

2[x + (7+x)] = 54

2x + 7 = 54/2

2x + 7 = 27

2x = 20

x = 10

7 + x = 17

Dimensions: 4x - y is less than or equal to 4 and 2x - 2y is greater than or equal to 3
