Question

The perimeter of a rectangle is 66cm.

Its longest side has a length of 17cm.
State the length of the shortest side.

Answer 1

`{ \red{\boxed{ \tt{Step-by-step-explaination}}}}`

Perimeter of a rectangle :
`{ \purple{ \tt{2(l+b)}}}`

length =
`{ \red{ \tt{17cm}}}`

breadth=
`{ \red{ \tt{?}}}`

now,

according to the rule.

perimeter = 2(l+b)

66 = 2(17+b)

66 = 34 + 2b

66 - 34 = 2b

32 = 2b

32/2 = b

16 cm = b

hence b =
`{ \pink{ \sf{16cm}}}`
