Question

a field length was 90 m and breadth 40 m raghu was tired to irrigate field . he lay down field irrigated ¼.
how much field was left to irrigate?​

Answer 1

Answer:

Area = 90 × 40 = 3200 m².

1/4 of 3200 = 800 m².

3200 - 800 = 2400 m².

Hence 2400 m² was left to irrigate.

Answer 2

Answer:

A field length was 90 m and breadth 40 m Raghu was tired to irrigate the field. If he lay downfield irrigated ¼, then 2700 sq. m. the field was left to irrigate.

Step-by-step explanation:

Length = 90 m

Breadth = 40 m

Area of rectangular field = length × breadth

= 90 × 40

= 3600 sq. m.

If he lay down field irrigated ¼ area = ¼ × 3600

= 900 sq. m

The  field was left to irrigate = 3600 - 900

= 2700 sq. m.
