Area and Perimeter- Missing side

Front

What is the definition of area?

Back

The space inside an object.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width) or P = 2L + 2W.

Front

If a rectangle has a perimeter of 34 meters and a width of 4 meters, how do you find the length?

Back

Use the formula P = 2L + 2W. Substitute P = 34 and W = 4, then solve for L.

Front

What is the perimeter of a rectangle with length 10 cm and width 3 cm?

Back

Perimeter = 2(10 + 3) = 26 cm.

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

If the area of a rectangle is 100 square inches and the width is 4 times the length, how do you find the dimensions?

Back

Let length = L, then width = 4L. Set up the equation L × 4L = 100 and solve for L.

Front

What is the relationship between the length and width of a rectangle if the width is 4 times greater than the length?

Back

Width = 4 × Length.

Front

What is the perimeter of a rectangle with a height of 11 cm and a width of 6 cm?

Back

Perimeter = 2(11 + 6) = 34 cm.

Front

What does it mean if a rectangle has a perimeter of 34 cm?

Back

The total distance around the rectangle is 34 cm.

Front

How can you find the missing side of a rectangle if you know the perimeter and one side?

Back

Rearrange the perimeter formula to solve for the missing side.
