question:-

The perimeter of a rectangular field is 340 yards. The length is 90 yd longer than the width. Find the dimensions.

Answer:-

  • width = 1.88
  • length = 91.88

let's find out

let X = width

X+90 = length

so,

  • 2x + 2(x+90) = 340
  • 2x + 2x + 180 = 340
  • 4x + 180 = 340
  • X = 340÷180
  • X = 1.88

therefore X = 1.88

so,

  • width = 1.88
  • length = 1.88 + 90 = 91.88

question:

The perimeter of a rectangular field is 360 yd. The length is 40 yd longer than the width. Find the dimensions.

AnsWer

Let x = width

x + 40 = length

2x + 2(x+40) = 360

4x + 80 = 360

4x = 280

x = 70

Width = x = 70 yd

Length = x + 40 = 110 yd

Answer:

length= 100 width=70

Explanation:

The perimeter of a rectangular field is 340 yds.

The length is 30 yds longer than the width.

2(l + w) = 340

l + w = 170

w + 30 + w = 170

2w = 140

w = 70

Hence the dimensions:

Length: 100 yds.

Width: 70 yds.
