Question

31. The length of a rectangle is 1 cm more than its breadth and its perimeter is 14 cm. Area of the rectangle is [JNV 1998] (1) 16 cm (2) 14 cm (3) 12 cm2 (4) 10 cm? 3​

Answer 1

Answer:

Let the length of the rectangle be=l

So, breadth is b=l−14

Perimetre= 2(l+b)=2(l+l−14)=180 cm

⟹4l−28=180cm

⟹l=52cm

And, b=52−14=38cm

Hence, Area=l×b=52×38=1976cm
