Question

the perimeter of a rectangle is 60 cm.if its breadth is 10 cm then what will be its length​

Answer 1

Answer:

breadth 10cm

perimeter 60cm

2×(l+b) = 60

2×l+10= 60

2× l =60-10

l = 50÷2

l= 25cm

Answer 2

Answer:

Length = 20cm

Step-by-step explanation:

Perimeter of a rectangle = 2(L + B)

Since the Length is twice the breadth that mean the Breath is 2xB = 2B

Perimeter of a rectangle = 2(2B + B)

Perimeter of a rectangle = 2(3B)

Perimeter of a rectangle = 6B

60= 6B

Breadth = 10

Length = 2x10= 20
