A researcher has a testing pot used for testing seeds. The perimeter of the plot is 322m. The length of the plot is 25m more than the width. Find the dimensions of the plot.

**w = width**

**w + 25 = length**{length is 25 more than the width}

**Perimeter of a rectangle = 2(width) + 2(length)**

2w + 2(w + 25) = 322 {substituted width and length into perimeter formula}

2w + 2w + 50 = 322 {used distributive property}

4w + 50 = 322 {combined like terms}

4w = 272 {subtracted 50 from each side}

w = 68 {divided each side by 4}

w + 25 = 93 {substituted 68, in for w, into w + 25}

**width = 68 m**

**length = 93 m**
