Question

the perimeter of a rectangle is 40 cm. the length of the rectangle is more than double it's breadth by 2 .find the length and breadth​

Answer 1

Answer:

HI mate.....

your answer is ......

Step-by-step explanation:

perimeter =40cm

length =breadth +(2*2)

breadth =b.

so,

perimeter =2(l+b)

40=2(b+(2*2)+b)

40=2(2b+4)

40=4b+8

4b=40-8

4b=32

b=32/4

b=8.

so, we found breadth =8cm

now, length =breadth +(2*2)

length =8+(2*2)

length =8+4

length =12.

therefore, length =12cm and breadth =8cm.
