Answer 1

Step-by-step explanation:

1. AREA OF A SQURE= side * side

Therefore, 169 = s * s

√169 = s

13 = s

HENCE, LENGTH & BREADTH OF SQUARE= 13cm

Now,perimeter = 4s

P = 4 * 13 = 52cm

2. Perimeter of rectangle = 2(l+b)

800cm (8 *100) = 2(80+b)

800 = 160+2b

800-160=2b

640/2=b

320cm= 3.2m = b

Area of rectangle = lb

area = 320 * 80

area = 25600cm^2 = 2.56m^2

3. Perimeter of square = 4* side

P= 4.84m= 484cm

Now, 484= 4s

484/4= s

121cm= 1.21m = s

Area of a square = side * side

area= 121 * 121

area = 14641cm^2 = 1.4641m^2
