The Ding-Dong doodad is a hot seller. The Top of its box has an area of 90 square centimeters. The box's top is 15 centimeters long. How wide is it? what is the doodad box tops perimeter?
W = ?
A = ?
A = LW
90 = 15W
P = 2L+2W
Ms. Sue
my answers are w = 6 and A = 42
would those be correct?
thank you
The width is 6.
The area is not 42.
sorry I meant 90
The perimeter is 42 centimeters.
To find the width of the Ding-Dong doodad box, we can use the formula for the area of a rectangle:
Area = Length x Width
We are given that the area of the top of the box is 90 square centimeters and the length is 15 centimeters. Therefore, we can rearrange the formula to solve for the width:
Width = Area / Length
Substituting the given values:
Width = 90 cm² / 15 cm
Width = 6 cm
Therefore, the width of the Ding-Dong doodad box is 6 centimeters.
To find the perimeter of the top of the box, we need to add up all the sides. In this case, since the top of the box is a rectangle, we can sum up the lengths of all four sides.
Perimeter = 2 x Length + 2 x Width
Substituting the given values:
Perimeter = 2 x 15 cm + 2 x 6 cm
Perimeter = 30 cm + 12 cm
Perimeter = 42 cm
Therefore, the perimeter of the Ding-Dong doodad box top is 42 centimeters.
