Answer:
435 in.²
Step-by-step explanation:
Surface area of the square pyramid = area of the square base + ½(Perimeter of base)(slant height)
Area of base = s²
s = 15 in
Area = 15² = 225 in²
Perimeter of the base = 4(15) = 60 in
Slant height = 7 in
Surface Area = 225 + ½(60)(7)
= 435 in.²

</span>Two-Thirds of the 96 members approved the plan
Question: What percent of the members did not approve of the plan?
=> two third means 2/3, thus there are 1/3 of them did not agree.
First to get the value let’s divide 96 by 3 .
=> 96 / 3 = 32
=> 32 * 6 = 64
32 = the number of people that did not agree with the plan
64 = is the total number of people that agree with the plan.</span>
