Answer:
33, 165, 133
Step-by-step explanation:
let the first number be n then
second number is 5n
third number is n + 100
sum the 3 numbers and equate to 331
n + 5n + n + 100 = 331 , that is
7n + 100 = 331 ( subtract 100 from both sides )
7n = 231 ( divide both sides by 7 )
n = 33
5n = 5 × 33 = 165
n + 100 = 33 + 100 = 133
the numbers are 33, 165, 133

5456 sq. inches
Let width = w,
Then length = w + 26
Perimeter = 2[length + width]
2[(w +26) + w] = 2[2w + 26] = 4w + 52
Perimeter given is 300
So, 4w + 52 = 300
4w = 248
w = 248/4 =62
length = 62 + 26 = 88
Area = length × width
Area = 88 × 62 = 5456 sq. inches
