Answer:
length= 100 width=70
Step-by-step 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.
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
