Find the surface area of the space figure represented by the net. 245.5 cm2

263 cm2

173.5 cm2

191 cm2

B. 263 cm²

Step-by-step explanation:

Surface area of the figure represented by the net = area of all parts of the net which consists of 3 rectangles and 2 triangles

✔️Area of the first two equal rectangles = 2(L*W)

L = 12 cm

W = 6 cm

Area of the first two equal rectangles = 2(12*6)

= 144 cm²

✔️Area of the third rectangle = L*W

L = 12 cm

W = 7 cm

Area = 12*7

= 84 cm²

✔️Area of the two equal triangles = 2(½*b*h) = b*h

b = 7 cm

h = 5 cm

Area = 7*5

= 35 cm²

✔️Surface area of the space figure = 144 + 84 + 35

= 263 cm²

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
