Answer:

120 mm²

800 in.²

Explanation:

Upper figure:

Large rectangle in the middle:

length = 5 mm + 6 mm + 5 mm = 16 mm

width = 6 mm

area = 16 mm × 6 mm = 96 mm²

2 congruent triangles:

base = 6 mm

height = 4 mm

area of each triangle = 6 mm × 4 mm / 2 = 12 mm²

Total area of net = 96 mm² + 2 × 12 mm² = 120 mm²

Lower figure:

Square in the middle:

side = 16 in.

area = 16 in. × 16 in. = 256 in.²

4 congruent triangles:

base = 16 in.

height = 17 in.

area of each triangle = 16 in. × 17 in. / 2 = 136 in.²

Total area of net = 256 in.² + 4 × 136 in.² = 800 in.²
