If I have a piece of poster board 22"x28" and I draw 1 1/4 inch squares can I draw?
It would help if you proofread your questions before you posted them.
How many 1.25" squares can you draw?
(22*28)/(1.25^2) = ?
Seems pretty clear to me. You have a standard poster board 22x28. How many 1.25 " squares can you get?
To determine if you can draw 1 1/4 inch squares on a 22"x28" poster board, we need to calculate how many squares can fit on the board.
Step 1: Convert the poster board dimensions to inches.
22" = 22 inches
28" = 28 inches
Step 2: Calculate the area of the poster board.
Area = Length x Width
Area = 22 inches x 28 inches
Area = 616 square inches
Step 3: Calculate the area of one square.
One square = 1 1/4 inches x 1 1/4 inches
One square = (5/4) inches x (5/4) inches
One square = 25/16 square inches
Step 4: Divide the area of the poster board by the area of one square to find out how many squares can fit.
Number of squares = Area of poster board / Area of one square
Number of squares = 616 square inches / (25/16) square inches
Number of squares = 616 square inches * (16/25) square inches
Number of squares = 3942.4 / 25
Number of squares = 157.696
Since you can't have a fraction of a square, you can draw 157 complete 1 1/4 inch squares on the 22"x28" poster board.
To determine whether you can draw 1 1/4 inch squares on a poster board measuring 22"x28", we can follow these steps:
1. Calculate the area of the poster board: Multiply the length by the width.
- Area = 22 inches x 28 inches = 616 square inches.
2. Determine the area of a single 1 1/4 inch square: Multiply the length by the width.
- Area of a square = 1.25 inches x 1.25 inches = 1.5625 square inches.
3. Divide the area of the poster board by the area of a single 1 1/4 inch square to find out how many squares you can draw:
- Number of squares = Area of poster board / Area of a square
- Number of squares = 616 square inches / 1.5625 square inches ≈ 394.24 squares (rounded to the nearest whole number).
Therefore, you can draw approximately 394 1 1/4 inch squares on a poster board measuring 22"x28".
