Draw a square of 9 square cm write A on it draw another square with double the side write B on it and answer These:
1)The perimeter of square A is _cm
2)The side of square B is_cm
3)The area of square B is _square cm
Answers
Answer:1) 12 cm
2)6 cm
3)36 square cm
Step-by-step explanation:
Area of square A=9 cm .Therefore side of A= square root of 9=3 cm.
Therefore perimeter of A=3*4=12cm
Side of B=3*2=6 cm(double the side)
Therefore Area of B=6*6=36 square cm.
Given : A square of 9 square cm
To Find : Draw another square with double the side. B Square
1. The perimeter of square A is _______ cm.
2. The side of square B is _______ cm.
3. The area of square B is _______ square cm.
4. The area of square B is _______ times the area of square A.
5. The perimeter of square B is _______ cm.
6. The perimeter of square B is _______ times the perimeter of square A.
Solution:
Square A Area = 9 cm²
Area of square = side²
=> side² = 9
=> side = 3 cm
Perimeter of Square = 4 x side
Perimeter of Square A = 4 x 3 =12 cm
Side of Square B = 2x 3 = 6 cm
Perimeter of Square B = 4 x 6 =24 cm
Area of Square B = 6² =36 cm²
Area of Square B / Area of square A = 36/9 = 4
Perimeter of Square B / Perimeter of square A = 24/12 = 2
1. The perimeter of square A is __12___ cm.
2. The side of square B is __6___ cm.
3. The area of square B is __36___ square cm.
4. The area of square B is __4____ times the area of square A.
5. The perimeter of square B is __24___ cm.
6. The perimeter of square B is ___2___ times the perimeter of square A.
