Question

What is the side length of square A, such that its area is equal to the area of four square B?

• A. $4$ sq ft
• B. $6$ sq ft
• C. $10$ sq ft
• D. $8$ sq ft

Answer 1

The correct option is A $4$ sq ft


Area of Square A = 4 $\times$ area of square $B$
Side length of square $B=2ft$
Area of Square $B=2\times 2=4sqft$
Area of Square $A=4\times 4=16sqft$
Area of Square $A=Side\times Side$
Hence, the side length of square $A=4ft$
