Question

A chart paper measures 4 m x 3 m. A strip of 1 m wide is cut out from all around. Find the area
of the remaining chart paper and the area of cut out strip.



explain step by step ​

Answer 1

Answer:

Area of remaining chart paper =9m^2

length of chart paper=4m

breadth of chart paper=3m

Area of chart paper=l×b=4×3=12m^2

length of cut out strip=1m

breadth of cut out strip=3m

Area of cut out strip=l×b=1×3=3m^2

Area of remaining chart paper=Area of chart

paper-Area of cut out strip

=12-3=9m^2

Hence, area of remaining chart paper is 9m^2.
