Go to the head of the class.
A. To find the perimeter of a rectangle, you add up the lengths of all four sides. Felic's rectangle has sides measuring 4 inches and 8 inches. So, the perimeter is calculated by adding twice the length and twice the width:
Perimeter = 2 * (Length + Width)
Perimeter = 2 * (4 + 8)
Perimeter = 2 * 12
Perimeter = 24 inches
Your answer of 24 inches is correct.
B. Hana's rectangle has a perimeter that is 2/3 as long as Felic's perimeter. To find Hana's perimeter, you multiply Felic's perimeter by 2/3:
Perimeter of Hana's rectangle = (2/3) * Perimeter of Felic's rectangle
Perimeter of Hana's rectangle = (2/3) * 24
Perimeter of Hana's rectangle = 16 inches
Your answer of 16 inches is correct.
C. To find the area of a rectangle, you multiply the length by the width. The length of Felic's rectangle is 4 inches and the width is 8 inches:
Area = Length * Width
Area = 4 * 8
Area = 32 square inches
Your answer of 32 square inches is correct.
D. Martin's rectangle has an area that is 25% (or 1/4) of Felic's area. To find Martin's area, you multiply Felic's area by 1/4:
Area of Martin's rectangle = (1/4) * Area of Felic's rectangle
Area of Martin's rectangle = (1/4) * 32
Area of Martin's rectangle = 8 square inches
Your answer of 8 square inches is correct.
Congratulations! Your answers are correct for all the questions.
