1.	1. A rectangular piece of ground is 45 m long and 30 m wide. It has two roads each 1 mwide, running midway within it, one parallel to the length and the other parallel to thebreadth. Find the area of the roads. Also calculate the area of the remaining ground.
Answer» Answer: A rectangular piece of ground is 45 m long and 30 m wide. It has TWO roads each 1 m wide, running MIDWAY within it, one parallel to the length and the other parallel to the breadth. Then the area of the roads, $= 1 \times 45 + 1 \times 30 - 1 \\ = 45 + 30 - 1 = 74 \: {m}^{2}$ The area of the REMAINING ground $45 \times 30 - 74 \\ = 1350 - 74 = 1276 \: {m}^{2}$

Answer:

A rectangular piece of ground is 45 m long and 30 m wide. It has TWO roads each 1 m wide, running MIDWAY within it, one parallel to the length and the other parallel to the breadth.

Then the area of the roads,

$= 1 \times 45 + 1 \times 30 - 1 \\ = 45 + 30 - 1 = 74 \: {m}^{2}$
