Question

How many rectangular plots of dimensions 40m by 60m can be made from a rectangular field of dimensions 120m by 160m?

Answer 1

number of plot = 120*160/40*60
= 8

Answer 2

Number of Plots which can be made is 9.

Step-by-step explanation:

Given,

• The Length of Rectangular Plots, l = 60 m

• The Breadth of Rectangular Plots,b = 40 m

Area of Rectangular Plots, a = $Length \times Breadth$

= $60 \times 40$

• Now, Length of Rectangular Field, L = 160 m

• Breadth of Rectangular Field, B = 140 m

Area of Rectangular Field, A = $Length \times Breadth$

= $160 \times 140$

Now, As per question, Number of Plots $\times$ Area of one Plot = Area of Field

or Number of Plots = $\frac {Area\ of\ Field}{Area\ of\ one\ Plot}$

= $\frac {160 \times 140}{60 \times 40}$

= $\frac {22400}{2400}$

= 9.33 or 9

So, Number of Plots which can be made is 9.
