The perimeter of sportsland park is 624 yd. the length of the rectangle park is 8 yd more than 3 times the width. find the dimensions of the park.

Let the width of the rectangular park be w yard . And it is given that the length is 8 yd more than 3 times the width . SO length is

The formula of perimeter of rectangle is

Substituting the given value of perimeter in the formula, we will get

So the width is 76 yd and the length is

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
