Question

B. Fill in the blanks -
1. If the sides of a square are halved then its area will become......................
2. Length and breadth of a rectangle are x and y, then its perimeter is......................
3. The area of a square is 49 sq. m then its perimeter is .........​

Answer 1

Answer:

( I ). area will be one times

(2). 2×( x+ y)

(3) area of sqare = 49sq.m

√a = √49

a= 7 m

perimeter= 4a

= 4× 7

= 28sq.m

this is the correct answer

Answer 2

Answer:

1. If the sides of a square are halved then its area will become its quarter.
2. Length and breadth of a rectangle are x and y, then its perimeter is 2 (x + y)
3. The area of a square is 49 sq. m then its perimeter is 28 m.

Assume that the sides of the square = x

x × x = 49

x² = 49

x² = 7 × 7

x = 7

Perimeter = side × 4

= 7 × 4

= 28 m

Hope it helps
