• A. $300$ square cm
• B. $70$ cm
• C. $70$ square cm
• D. $300$ cm

Answer 1

Answer: (A), (B)

$70$ cm

Length of the rectangle $=20$ cm
Breadth of the rectangle $=15$ cm

Perimeter is the sum of all the sides of the shape and the rectangle has opposite equal sides:


So, the perimeter $=20+15+20+15=70$ cm

And, area of a rectangle is product of its length and breadth
$=20\times 15=300$ square cm
