Answer:
112 yd²
Step-by-step explanation:
Surface area of the square pyramid = area of base + perimeter of base × slant height
Area of base = s²
s = 4 yd
Area = 4² = 16 yd²
Perimeter = 4(s)
Perimeter = 4(4) = 16 yd
Slant height = 6 yd
Surface area of the square pyramid = 16 + 16 × 6
= 16 + 96
= 112 yd²

Step-by-step explanation:
The area of the rectangle is 15*5= 75 inches
The area of the 2 semicircles combined, which make a circle, are:
π*r², where r is 5
r²=25
π*25=78.53981633
75 + 78.53981633 is about 154
Double the number then triple that number
