common difference (d) = 11-7 = 4
Recursive rule: A(n) = A(n-1) + d = A(n-1) + 4
Explicit rule: A(n) = A(1) + d * (n-1) = A(1) + 4 *(n-1) = 7 + 4 * (n-1) = 4n + 3
15th term: A(15) = 4 * 15 + 3 = 63
Formula for area of triangle is Base times height divided by 2 equals Area
Or
B×H÷2=Area so it would be
15.25×18=274.5
Divided by 2 =137.25 inches
Answer:
94cm squared
Step-by-step explanation:
you find the area of each side by doing base times height and you add the six of them all together to get your answer
