Question

PLS ANSWER U WILL BE MARKED AS BRAINIEST

Answer 1

Answer:

length be 2x

perimeter = 36cm

= 2 ( x + 2x )

= 2x + 4x

= 36 = 6x

x = 36/6 = 6cm

breadth = 6cm

length = 12cm

Step-by-step explanation:

d. 12

Answer 2

Step-by-step explanation:

Let the breadth be x cm

So length = 2×x cm = 2x cm

Perimeter = 36 cm

By condition,

2(L+B) = Perimeter

2(2x+x) = 36

4x+2x = 36

6x = 36

x = 36/6

x = 6

So the length is (2×6) cm =12 cm

The correct option is d) 12
