Question

draw a rectangle whise area is 30 sq cm​

Answer 1

Area of rectangle

• L × B

Area square = 30 sq cm

• L × B = 30 SQ CM

WRITE

• L = 1

• B = 2 = L + 2 = 1 + 2 = 3

• L × B = 30 SQ CM

• 1 × 3 = 30 SQ CM

• 3 = 30 SQ CM

• ==> 30 / 3

• ==> 10 SQ CM

Length of rectangle =

• ==> L = 1 × 10 = 10 SQ CM

• ==> B = 3 × 10 = 30 SQ CM

Area of rectangle =

• 10 SQ CM × 30 SQ CM = 300 SQ CM
