sides in sq. m.
(i) 6.8 m (ii) 320 cm (iii) 4.8 dm​

Answer 1

(i) Area Of Square = 46.24 m²

(ii) Area Of Square = 1024 m²

(iii) Area Of Square = 2.209 m²

Step-by-step explanation:

GIVEN NUMBERS

(i) 6.8 m

(ii) 320 m

(iii) 4.8 dm

___________________________

TO FIND

Area

___________________________

FORMULAS OF SQUARE

Area Of Square = Side × Side = Side²

Perimeter Of Square = 4 × side

Diagonal Of Square = Side√2

___________________________

SQUARE

• All sides of square are of equal measure.

• All angles of square aee of 90°.

___________________________

(i) 6.8 m

Area Of Square = Side × Side = Side²

Area Of Square = 6.8 × 6.8

Area Of Square = 46.24

Area Of Square = 46.24 m²

___________________________

(i) 320 cm

Area Of Square = Side × Side = Side²

Area Of Square = 320 × 320

Area Of Square = 102400 cm

Area Of Square = 102400 cm²

100 cm = 1 m

m = 102400 / 100

m = 1024

Area Of Square = 1024 m²

___________________________

(iii) 4.7 dm

Area Of Square = Side × Side = Side²

Area Of Square = 4.7 × 4.7

Area Of Square = 22.09 dm

Area Of Square = 22.09 dm²

1 dm = 0.1 m

m = 22.09 / 10

m = 2.209

Area Of Square = 2.209 m²

Answer 2

Answer:

1) 46.24

2) 10.24

3)0.2304
