Word Problem converted to number form

The lenght of a rectangle is 8 feet more than two times it width. Ther perimeter is 400 feet. find the length and width

Perimeter formula

P = 2L + 2W

400 = 2(8 + 2w) + 2w

400 = 16 + 4w + 2w

The distributive property

400 = 16 + 6w

Collecting like terms

400 = 16 + 6w
-16 - 16

Subtracting - 16 from both sides

384 = 6w

384/6 = 6w/6

Dividing 6 from both sides

64 = w

A number form is a mental map of numbers, which automatically and involuntarily appears whenever someone who experiences number-forms thinks of numbers. Number forms were first documented and named by Sir Francis Galton in his The Visions of Sane Persons (Galton 1881a). Later research has identified them as a type of synesthesia (Seron, Pesenti & Noël 1992; Sagiv et al. 2006). In particular, it has been suggested that number-forms are a result of "cross-activation" between regions of the parietal lobe that are involved in numerical cognition and spatial cognition (Ramachandran & Hubbard 2001; Hubbard et al. 2005).
