Question

through a rectangular field of length 100cm and breadth 70 m two cross roads are built which is parallel to the side and cut each other at right angle through the center of the field if the width of each road is 5 m find the area covered by the cross roads​

Answer 1

Step-by-step explanation:

Area  of a rectangle is 6 times the area of a small rectangle

Length of both the rectangles are equal

Let the breadth of smaller rectangle be x

Given,

Breadth of bigger rectangle =2x

∴6×l×x=l×2

⇒x=62

⇒x=31
