Question

The area of a rectangular sheet is 600 sq cm.If the length is 30 cm, find its perimeter​

Answer 1

Answer:

length is 30

area is 600

breadth is 600 =30×b

600/30 =b

20=b

perimeter=2(L+B)

2(30+20)

2(50)

100

ans is 100cm²

Answer 2

Answer:

100cm

Step-by-step explanation:

Area of rectangle= l×b

600cm² = 30cm × b

600cm²/30cm = b

20cm = breadth

Perimeter of rectangle = 2(l+b)

= 2( 30cm + 20cm)

= 2× 50cm

=100cm
