The area of an 12-cm-wide rectangle is 252 cmsquared. What is its length? please show steps on how you get the answer I dont even understand where to start
area = length * width, so
length = area / width = 252cm^2 / 12cm = 21cm
To find the length of the rectangle, we can use the formula for the area of a rectangle, which is length multiplied by width.
Step 1: Write down the given information:
Width = 12 cm
Area = 252 cm²
Step 2: Use the formula to set up an equation:
Length * Width = Area
Let's substitute the given values into the equation:
Length * 12 cm = 252 cm²
Step 3: Solve for length by isolating the variable:
Divide both sides of the equation by 12 cm to solve for length:
Length = 252 cm² / 12 cm
Step 4: Simplify the division:
Length = 21 cm
Therefore, the length of the rectangle is 21 cm.
