Elena walked 12 miles. Then she walked 1/4 that distance. How far did she walk all together? Select all that apply. Select all that apply:
12 + (1/4)
12 • (1/4)
12 + (1/4) • 12
12 (1 + (1/4))
12 • (3/4)
12 • (5/4)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
