1. One face is 5.1*2.5=12.75 un^2, one is 8.5*2.5=21.25, one is 6.8*2.5=17, and two are 1/2*6.8*5.1, so both are 34.68. Total is 85.68, rounded to 85.7 cm^2. (C)
2. The area of the circles is 2(π*2^2), which is about 25.1. The rectangle's area can be found as 2π*2*3, which is about 37.7. The total is rounded to 62.8 m^2 (D)
3. Rectangular faces: 3.6*1.8=6.48, 8.5*1.8=15.3, 7.7*1.8=13.86
Triangles: 2(1/2(3.6*7.7))=27.72
Total: 63.36, round to 63.4 km^2 (B)

so off estimation its 10
Answer:
1. First box, the missing fraction = 1/10
2. For the 2nd box
a. The missing fraction = 3/10
b. Percentage = 30%
3. For 7/10
Percentage = 70%
Step-by-step explanation:
From the question given above, the following data were obtained:
The strip is divided into 10 equal parts.
1. For the first box:
The missing fraction = 1/10
2. For the 2nd box
a. The missing fraction = 3/10
b. Percentage = 3/10 × 100 = 30%
3. For 7/10
Percentage = 7/10 × 100 = 70%
You just cross multiply and then simplify
