Answer:
Length = 3
Step-by-step explanation:
the formula for area of a rectangle is Area = Base (width) x Height (length)
so plug in out values: 3/2 = 1/2 x H
divide both sides by 1/2 to find the height/length: 3/2 ÷ 1/2 = Height
to divide a fraction by a fraction, flip the divisor and change the sign from ÷ to ×
so you get 3/2 × 2/1 = Height
the 2 cancels out, so you get: 3 = height/length
