Answer:
The answer would be 31.5
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.
