Solve these word problems.

1. The length of a rectangular field is 42 meters more than the width. Its perimeter is 600 meters. Find its dimensions.
P=21+ 2w
Coo = 21421+
ctangular piece of wood is 12 centimeters longer than it is wide. A strip 1 centimeter wide is cut off all around.
The decreases the area by 120 square centimeters. What were the original dimensions?
Let w = original width.
1 = w+ 12 cm = original length
W-2 cm = new width
W + 12 cm - 2 cm = w+ 10 cm = new length
3. A rectangle's wi
length. Its area is 338 square centimeters. What are its dimensions?
A=Iw
348= 2L

Answer 1

Answer: 1) Length = 171 meters, width = 129 meters

Explanation:

Length = w + 42

width = w

Perimeter = 600

Perimeter = 2(Length) + 2(width)

600 = 2(w + 42) + 2(w)

600 = 2w + 84 + 2w

600 = 4w + 84

516 = 4w

129 = w

Length = w + 42

= 129 + 42

= 171
