Area and Perimeter Part 2

Front

What is the formula for calculating the area of a rectangle?

Back

A = l x w (Area = length x width)

Front

If the length of a rectangle is 10 and the width is 5, what is the area?

Back

A = 10 x 5 = 50

Front

What is perimeter?

Back

Perimeter is the total distance around a shape.

Front

If a rectangle has a length of 20 and a width of 10, what is the perimeter?

Back

P = 2(l + w) = 2(20 + 10) = 60

Front

What is the width of a rectangle if the perimeter is 40 and the length is 15?

Back

Width = (Perimeter/2) - Length = (40/2) - 15 = 5

Front

If the area of a rectangle is 72 and the length is 8, what is the width?

Back

Width = Area / Length = 72 / 8 = 9

Front

What does it mean to break apart numbers in multiplication?

Back

It means to split a number into smaller, easier parts to simplify calculations.

Front

If you have a rectangle with a length of 12 and a width of 4, what is the area?

Back

A = 12 x 4 = 48

Front

What is the perimeter of a square with each side measuring 6?

Back

P = 4 x side = 4 x 6 = 24

Front

If the area of a rectangle is 50 and the width is 5, what is the length?

Back

Length = Area / Width = 50 / 5 = 10
