Answer:
The two numbers are 476 and 284
Step-by-step explanation:
Given:
He used an even number of blocks
The number of blocks is between 700 and 800
The number of blocks is the sum of two
To Find :
Two number = ?
Solution:
The sum of an odd number and an even number id always odd. So 423 can be eliminated
So two numbers must be any of the 4 remaining options
Its also given that the number lies between 700 and 800. So the sum should be greater than 700 and lesser than 800
by trial and error method
352+476 = 828 ( greater than 700 but greater than 800, condition fails)
352+326 = 678 ( lesser than 700 but lesser than 800, condition fails)
352+284 = 636 ( lesser than 700 but lesser than 800, condition fails)
476+326 = 802 ( greater than 700 but greater than 800, condition fails)
476+284 = 760 ( greater than 700 and lesser than 800)
Answer:
b
Step-by-step explanation:
The area of a square = s² ← s is the length of the side, hence
s² = 800 ( take the square root of both sides )
s = ≈ 28.28
28.28 is between 28 and 29 → b
