a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

$2(l + b)$

So therefore

$2(8x + 3 + 5) = a$

$= > 16x+ 6 + 10 = a$

$= > 16x + 16 = a$

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

$(8x + 3) \times 5$

$= 40x + 15$

Answer = b) that is area is 40x + 15

Answer:

The number is 385.

Step-by-step explanation:

The 5 is in the ones place so you put that at the end. The digit in the tens place is 3 plus the digit in the ones place which is 5 so 3 + 5 = 8 so the 8 is in the tens place. The digit in the hundreds place is 2 less than the digit in the ones place which is 5 so 5 - 2 = 3 so the 3 is in the hundreds place
