Can someone please help me with this?

65 mm²

Step-by-step explanation:

Total surface area of the prism = area of all parts of the prism's net

✔️Area of rectangle 1 with the following dimensions:

L = 5.2 mm

W = 2.1 mm

Area = 5.2*2.1 = 10.92 mm²

✔️Area of rectangle 1 with the following dimensions:

L = 5.2 mm

W = 4.5 mm

Area = 5.2*4.5 = 23.4 mm²

✔️Area of rectangle 3 with the following dimensions:

L = 5.2 mm

W = 5 mm

Area = 5.2*5 = 26 mm²

✔️Area of the 2 traingles with the following dimensions:

b = 4.5 mm

h = 2.1 mm

Area = ½*bh

= ½*4.5*2.1

= 4.725 mm²

Total surface area = 10.92 + 23.4 + 26 + 4.725 = 65.045 ≈ 65 mm² (nearesth while number)

-14 is the answer

hope this : ))
