Question

Find the area of rectangle whosexlengthis
12cm perimeter 120 cm.​

Answer 1

Perimeter of a rectangle= 2 (l+b)=120cm. (Given)

Length of rectangle =12cm=l

Breadth of rectangle =?=b

Substituting value of l

2 (12+b)=120cm

12+b=120/2

12+b=60

b=60-12

b=48cm

Area of rectangle =l×b

=12×48

=576cm^2
