Perimeter of Rectangle = 2 (length) + 2 (width)
Width: x
Length: x + 12
Perimeter: 100
Solution:
100 = 2(x + 12) + 2 (x)
100 = 2x + 24 + 2x
4x = 100 - 24
4x/4 = 76/4
x = 19
Dimensions:
Width: x = 19 cm
Length: 19 + 12 = 31 cm
Area = (length) (width)
Area = (31 cm) (19 cm)
Area = 589 cm²
ANSWER: The area of the rectangle is 589 cm².
