Area Calculation Using Grid Squares Quiz

To find the area of a rectangle, multiply its width by its height. In this case, the rectangle is 5 squares wide and 3 squares tall. Therefore, the area is calculated as 5 (width) x 3 (height) = 15 square units.

The area of a square is calculated by squaring the length of one of its sides. In this case, each side measures 4 grid squares. Therefore, the area is 4 × 4, which equals 16 square units.

The area of a shape can be determined by counting the number of complete squares it contains. Since the grid shows 24 complete squares within the shape, the area is equivalent to the total number of squares, which is 24 square units.

To find the area of a rectangle, multiply its length by its width. In this case, the rectangle measures 6 units in length and 2 units in width. Therefore, the area is calculated as 6 × 2 = 12 square units.

To find the number of unit squares in a 7 × 5 rectangle, multiply the length by the width. Thus, 7 (length) multiplied by 5 (width) equals 35. Therefore, a 7 × 5 rectangle contains 35 unit squares.

A square's area is calculated by squaring the length of one side. Given an area of 9 square units, we find the side length by taking the square root of 9. Thus, the side length is 3 units, as 3 x 3 = 9.

To find the total area of the L-shaped figure, calculate the area of each rectangle separately. The area of the 4 × 3 rectangle is 12 square units, and the area of the 2 × 2 rectangle is 4 square units. Adding these together gives 12 + 4 = 16 square units, which is the total area.

To find the length of a rectangle, use the formula for area: Area = Length × Width. Given the area is 20 square units and the width is 4 units, you can rearrange the formula to find the length: Length = Area / Width = 20 / 4 = 5 units.

The area of a square is calculated by squaring the length of one of its sides. In this case, each side of the 3 × 3 square measures 3 units. Therefore, the area is 3 × 3 = 9 square units.

To cover 18 unit squares, the area of the shape must equal 18. The dimensions 3 × 6 yield an area of 18 (3 multiplied by 6 equals 18), making it a valid option. Other combinations either exceed or do not meet the required area of 18 unit squares.

A rectangle that covers 8 grid squares can be expressed in terms of its dimensions. Given one side is 4 units, the other side must be calculated as follows: Area = length × width. Thus, 8 = 4 × width, leading to a width of 2 units. Therefore, the rectangle can be 4 × 2 units.

Both rectangles have the same area, calculated by multiplying their dimensions. The area of the 5 × 4 rectangle is 20 square units (5 × 4 = 20), and the area of the 10 × 2 rectangle is also 20 square units (10 × 2 = 20). Since both areas are equal, the statement is true.
