Given:-

• one side = 4m
• diagonal=5m

To find:-

• Area of rectangle.

Solution:-

By using Pythagoras theorem other side of rectangle can be determined.

From here

Now we have two sides of rectangle and area of rectangle is given by product of sides

hence

Area= 3 x 4= 12m²

Answer:

12m²

Step-by-step explanation:

5 2 - 42

= √ 9

=3 m

So The area of the rectangular field = 4 x 3

= 5 2 - 42

= √ 9

=3 m

So The area of the rectangular field = 4 x 3

= 12m²

Hope it helps..
