Question

Find the area of rectangle whose side's are 3cm, 4cm, 12m,. 21 m

Answer 1

Answer:

Area of 1'st rectangle = 12cm²

Area of 2'nd rectangle = 252m²

Step-by-step explanation:

Length of 1'st rectangle = 3 centimetres

Breadth of 1'st rectangle = 4 centimetres

Length of 2'nd rectangle = 12 metres

Breadth of 2'nd rectangle = 21 metres

Area of a rectangle = length × breadth

Area of 1'st rectangle = length of 1'st rectangle × breadth of 1'st rectangle

Area of 1'st rectangle = 3cm × 4 cm

Area of 1'st rectangle = 12cm²

Area of 2'nd rectangle = length of 2'nd rectangle × breadth of 2'nd rectangle

Area of 2'nd rectangle = 12m × 21m

Area of 2'nd rectangle = 252m²

Hence, the area of 1'st rectangle is 12 cm² And area of 2'nd rectangle is 252 m²
