Question

the area of a rectangular is 120 sq.cm. if it's length is 15 cm , what is it's perimete?​

Answer 1

Step-by-step explanation:

Area of rectangle = l ×b

and Area of rectangle = 120 sqcm and l=15 cm( given)

so, l×b = 120

15×b =120

b =120/15

b = 8 cm

Perimenter of rectangle = 2(l+b) = 2(15+8)=2×23= 46 cm
