the perimeter of a rectangle is 96cm ,the width is 15cm find its lengh. this is homework wich i have to return on friday,plllllllllllleeeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaassssssssssssseeeeeeeeeeeeee
P = 2L + 2W
96 = 2L + 30
66 = 2L
? = L
thankyou STAR
To find the length of a rectangle, you need to use the formula for the perimeter of a rectangle, which is the sum of all its sides.
In this case, we know the perimeter is 96 cm, and the width is 15 cm. Let's denote the width as "w" and the length as "l".
The formula for the perimeter of a rectangle is:
Perimeter = 2 * (length + width)
In this case, we have:
96 cm = 2 * (l + 15 cm)
To solve for the length, we can simplify the equation:
48 cm = l + 15 cm
Now, subtract the width (15 cm) from both sides to isolate the length (l):
48 cm - 15 cm = l
33 cm = l
Therefore, the length of the rectangle is 33 cm.
