Answer 1

☆ Solution ☆

(i) Length = 15 m, breadth = 9 m

=> As we know that :-

Area of rectangle = l × b

Where,

• L = 15 m

• B = 9 m

Putting the respective value,

Area of rectangle = 15 × 9

Area of rectangle = 135

Hence,

Area of rectangle = 135 m²

(ii) Length = 32 m, breadth = 24 m

=> As we know that :-

Area of rectangle = l × b

Where,

• L = 32 m

• B = 24 m

Putting the respective value,

Area of rectangle = 32 × 24

Area of rectangle = 768

Hence,

Area of rectangle = 768 m²

(iii) Length 5 m, breadth = 3.5 m

=> As we know that :-

Area of rectangle = l × b

Where,

• L = 5 m

• B = 3.5 m

Putting the respective value,

Area of rectangle = 5 × 3.5

Area of rectangle = 17.5

Hence,

Area of rectangle = 17.5 m²

______________________________

(iv) Length = 4.5 m, breadth = 2 m

=> As we know that :-

Area of rectangle = l × b

Where,

• L = 4.5 m

• B = 2 m

Putting the respective value,

Area of rectangle = 4.5 × 2

Area of rectangle = 9

Hence,

Area of rectangle = 9 m²

(i) Length = 15 m, breadth = 9 m

{°} As we know that :-

Area of rectangle = l × b

Where,

L = 15 m

B = 9 m

Putting the respective value,

Area of rectangle = 15 × 9

Area of rectangle = 135

Hence,

Area of rectangle = 135 m²

______________________________

(ii) Length = 32 m, breadth = 24 m

=> As we know that :-

Area of rectangle = l × b

L = 32 m

B = 24 m

Putting the respective value,

Area of rectangle = 32 × 24

Area of rectangle = 768

Hence,

Area of rectangle = 768 m²

______________________________

(iii) Length 5 m, breadth = 3.5 m

=> As we know that :-

Area of rectangle = l × b

Where,

L = 5 m

B = 3.5 m

Putting the respective value,

Area of rectangle = 5 × 3.5

Area of rectangle = 17.5

Hence,

Area of rectangle = 17.5 m²

______________________________

(iv) Length = 4.5 m, breadth = 2 m

=> As we know that :-

Area of rectangle = l × b

Where,

L = 4.5 m

B = 2 m

Putting the respective value,

Area of rectangle = 4.5 × 2

Area of rectangle = 9

Hence,

Area of rectangle = 9 m²
