Question

The area of a rectangle is 102sqcm. If it's length is 17cm,what is it's perimeter

Answer 1

area of rectangle =l*b
so l=17*b=102
b=102/17=6
so perimeter =2(l+b)
2(17+6)
2*23
46 cm

Answer 2

Area of a rectangle= l×b
102sqcm = 17cm × b
102sqcm/17cm = b
6cm = b
So, the breadth is 6cm

perimeter of a rectangle= 2(l+b)
= 2(17+6)cm
= 34cm+12cm
= 46cm

Therefore, Perimeter of the rectangle is 46 cm
