What is the formula to find the area of a rectangle?

Back

A = L x W (Area = Length x Width)

Front

What is the formula to find the area of a square?

Back

A = S x S (Area = Side x Side)

Front

If the area of a square is 25, what is the length of one side?

Back

5 (Since A = S x S, S = √25 = 5)

Front

What is the perimeter of a square with a side length of 5?

Back

20 (Perimeter = 4 x Side = 4 x 5 = 20)

Front

How do you calculate the total cost if one item costs $10 and you buy 5 items?

Back

Total Cost = Price per Item x Number of Items = $10 x 5 = $50

Front

What is the area of a rectangle with a length of 4 units and a width of 3 units?

Back

12 units squared (A = L x W = 4 x 3 = 12)

Front

What is the formula for the perimeter of a rectangle?

Back

P = 2L + 2W (Perimeter = 2 x Length + 2 x Width)

Front

If a rectangle has a length of 6 and a width of 2, what is its area?

Back

12 units squared (A = L x W = 6 x 2 = 12)

Front

What is the area of a square with a side length of 7?

Back

49 units squared (A = S x S = 7 x 7 = 49)

Front

If the area of a rectangle is 30 and the width is 5, what is the length?

Back

6 (Since A = L x W, L = A / W = 30 / 5 = 6)
