Writing and solving an equation from geometry length and area word problems.

• How do you write and solve an equation from geometry length and area word problems?
• If an isosceles triangle has two equal sides, the shortest side is 4 feet shorter than one of the equal sides, and the perimeter is 38 feet, what is the length of the shortest side of the triangle?
• If n - 4 + n + n = 38, what is n?
• If the length of a rectangular parking lot is 10 meters less than twice its width, and the perimeter is 400 meters, what is the length of the lot?
• How can you draw a picture to help you solve a geometry word problem?
• How do you solve for w if w + 2w - 10 + w + 2w - 10 = 400?
• What is the shortcut to solving a perimeter word problem?
• How do you check your solution to a word problem?
