Answer 1

Answer:

5.25

Step-by-step explanation:

1. a^2+a^2=5√2^2
2. 2a^2=25(2)
3. 2a^2=50
4. a^2=50/2
5. a^2=25
6. a=√25
7. a=5

area=a^2=5^2=25

hope it helps you

Answer 2

Step-by-step explanation:

• Q1. Perimeter of Square = 27.6 cm
• So In order to get Area we need Side
• We kbow that Perimeter of Square =
• P = 4 × side
• So 27.6 / 4 = 6.9 cm
• Side = 6.9 cm
• Now Area = side × side
• 6.9 × 6.9 = 47.61 cm
• Area = 47.61 cm

Q2.

• Given :
• Area of Rectangle = x
• Length of Rectangle = 7.45 cm
• Perimeter = 24.5 cm

In order to find area we need Breadth ,

• B = P / 2 - L
• B = 24.5 / 2 - 7.45 cm
• B = 4.8

Now be have both length and breadth ,

• Area of Rectangle = L × B
• Area = 7.45 × 4.8
• Area = 35.76
