Question

The figure shows two paths drawn inside a rectangular field 60 m long and 30 m wide. If the width of each path is 5 m, then the area of the shaded portion is ___ sq. m.

• A. 475
• B. 450
• C. 425
• D. 400

Answer 1

The correct option is C

425

Area of shaded region = Area of path 1+ Area of path 2 - Area in the centre of both the paths which has been taken twice.
Area of shaded region $=(60\times 5)+(30\times 5)-(5\times 5)$

$=5(60+30-5)$

$=5\left(85\right)$

$=425\text{sq.m}$
