wide, running midway within it, one parallel to the length and the other parallel to the
breadth. Find the area of the roads. Also calculate the area of the remaining ground.​

Answer 1

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

$45 \times 30 - 74 \\ = 1350 - 74 = 1276 \: {m}^{2}$
