Answer:

The answer would be 31.5

Step-by-step explanation:

First it's a rectangular

Second we would convert the fraction to decimal so 1 1/2 would be 1.5 and 2 1/2 would be 2.5

so the formula of the rectangular 2(wl + hl + hw)

so 2(1.5 × 2.5 + 3 × 2.5 + 3 + 1.5)

it would be 31.5 if we do the math

hope it helped.
