Question

If the length of a rectangle is (2*H) more than its breadth x-2, then find its perimeter.​

Answer 1

Answer:

20 cm

Step-by-step explanation:

Let the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

⇒70=2(x+(x+5))

⇒

2

70

=2x+5

⇒2x+5=35

⇒2x=35−5=30

⇒x=

2

30

=15cm

Breadth=x=15cm and length=x+5=15+5=20cm
