Answer 1

Answer:

The length of a rectangle is twice its breadth . If perimeter is 36 cm then its length is ________

a) 4 b) 8 c) 10 d) 12

Step-by-step explanation:

12

Answer 2

Step-by-step explanation:

perimeter= 2(length) + 2 (breath)

given: length = 2(breath)

so,

perimeter= 2(2breath) +2(breath). because L=2B

P= 4B + 2B

P= 6B

36=6B. because P=36cm. give

or 6B=36

or B =36/6

or B =6

since length is twice of breath

therefore

length =6 x 2 = 12 cm
