Question

How many rectangular plots of land 40 m × 20 m can be cut from a square field of side 100 m?

Answer 1

Answer :

12.5 rectangular plots can be cut from the given square field.

Step-by-step explanation :

Given :

Dimensions of each rectangular plot = 40 m × 20 cm

Side of the square field = 100 m

To find :

the number of rectangular plots cut from the square field

Solution :

 Let "n" be the number of rectangular plots

To find it, we have to find the area of one rectangular plot and area of the square field.

Then, we can find the number of rectangular plots by dividind the area of the square field by the area of rectangular plot.

So, let's find the areas.

⇒ Area of square field = side × side

   Area of square field = 100 m × 100 m

   Area of square field = 10000 m²

⇒ Area of one rectangular plot = 40 m × 20 m

   Area of one rectangular plot = 800 m²

We assumed the number of rectangular plots as "n"

So,

The number of rectangular plots × area of each rectangular plot = area of the square field

Substitute the values,

 n × 800 m² = 10000 m²

 n × 800 = 10000

 n = 10000/800

 n = 100/8

 n = 12.5

Therefore, the number of rectangular plots are 12.5
