Hello,
The correct answer is B) 280 in²
= 10( 2 × 9 + 10 )
= 10 (2 × 9 = 18 + 10 = 28)
= 10 × 28 = 280
= 280
Answer: 280 in²
In other words.....
= 10(2*9+10)
= 10(18+10)
= 10*28
= 280
Answer: 280 in²

Answer:
Age of Jacob is 10 years.
Step-by-step explanation:
Let the age of Jacob = x years and age of Kinsley = y years
Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"
y = 2x - 7
By second statement " Kensley is 13 years old "
y = 3 years
By putting y = 13 years in the equation
13 = 2x - 7
2x = 13 + 7
2x = 20
x = = 10 years
Therefore, age of Jacob is 10 years.
