Goal: Practice using division to identify the missing side of a rectangle.
Finding clues is the key to finding the missing side of a rectangle. Use what you know to solve the problem.
Remember: Area \({=}\) length \({\times}\) width or \({\Large\text{A}= l \times w}\).
What’s the missing side?
What is the length of the missing side?
Rectangle width: 3 meters, Area 18 square meters, length
question mark.
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\). So, \({\Large18\;\text{sq. m} = \text{?} \times 3\text{m}}\).
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\). So, \({\Large18\;\text{sq. m} = \text{?} \times 3\text{m}}\).
Correct! The length of the missing side is 6 meters.
What is the length of the missing side?
Rectangle width: question mark, length 10 feet, Area 60
square feet.
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
Correct! The missing length of the missing side is 6 ft.
What is the length of the missing side?
Rectangle width: 4 centimeters, length question mark,
Area 20 square centimeters.
Correct! The missing length of the missing side is 5 cm.
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
What is the length of the missing side?
Square width: question mark, length 8 feet, Area 64
square feet.
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
To find the missing side, use the equation for finding Area, \({\Large\text{A} = l \times w}\).
Correct! The missing length of the missing side is 5 cm.
