Question

five square flower beds ecah of side 1 m are dug on a peice of land 5 m long and 4 m wide .
what is the area of reamaning part of the land?​

Answer 1

Answer:

Given:five square flower beds each of side 1 m

Length of land is :5m, b:4m

To find:area of remaining part of the land.

= Area of five square flower =>5×(side)²

=>5× (1)²

=>5m²

Area of land= l×b

=5×4=20m²

so, remaining area=20-5=15m²

so, Our required answer is 15m²

remaining area of land is 15m²

Answer 2

Solution:

We will be using the area of square formula for finding the area of five square flower beds and the area of the rectangle formula for calculating the area of the piece of land.

From the given figure we see that,

Five 1 m square flower beds dug on a 5 m long and 4 m wide piece of land.

Let us calculate the area of the flower square bed

Area of flower square bed = side × side

⇒ Area of flower square bed = 1 × 1 = 1 m2

Thus, area of 5 square beds = 1 × 5 = 5 m2

Now, Area of the land = Length × Breadth

⇒ Area of the land = 5 × 4 = 20 m2

Now, the remaining part of the land = Area of land – Area of 5 square beds

= 20 – 5

= 15 m2

Therefore, the area of the remaining part of the land is 15 sq m.
