Answer:
Area = 84 cm^2
Perimeter = 38 cm
Explanation:
The shape is a rectangle.
Area of the rectangle:
The formula for the area of a rectangle is given by:
A = lw, where
- A is the area in units squared,
- l is the length,
- and w is the width
Thus, we can plug in 7 for l and 12 for w to find A, the area of the rectangle in cm^2:
A = 7 * 12
A = 84
Thus, the area of the rectangle is 84 cm^2.
Perimeter of the rectangle:
The formula for the perimeter of a rectangle is given by:
P = 2l + 2w, where
- P is the perimeter,
- l is the length,
- and w is the width.
Thus, we can plug in 7 for l and 12 for w to find P, the perimeter of the rectangle in cm:
P = 2(7) + 2(12)
P = 14 + 24
P = 38
Thus, the perimeter of the rectangle is 38 cm.
