Answer 1

Answer:

The area of the plot is 38.5 km²

Step-by-step explanation:

Given:

• The plot is rectangular and is 7 km long

• 5 km 500 m broad

To find :

• The area of the plot in square kilometres

Solution:

Convert

⇒ 5 km 500 m in km

⇒ 5000 + 500 = 5500

⇒ 5500 / 1000

⇒ 5.5 km

★ Breadth = 5.5 km

★ Length = 7 km

Now,

Area of rectangle = length × breadth

⇒ 7 × 5.5

⇒ 38.5 km²

Therefore,

The area of the plot is 38.5 km²
