Question

breadth of a rectangle is 4 times its length if its perimeter is 60 cm find its length​

Answer 1

✨Your Answer✨

Let the length be x cm and the breadth be 4x cm.

So, 2 × ( x + 4x ) = 60

=> 2 × 5x = 60

=> 10x = 60

=> x = 6

Therefore the length of the rectangle is 6 cm.

Answer 2

$\boxed{ \huge \pink{ \mathfrak{solution}}}$

Given :

Breadth of the rectangle is 4 times of its length. so,

Let

• length = x

and

•breadth= 4x

• Perimeter of the rectangle is 60 cm

$\bold{ \rightarrow} \: 60 = 2(l + b) \\ \\ \rightarrow \: 60 = 2(x + 4x) \\ \\ \rightarrow \: 60 = 2x + 8x \\ \\ \rightarrow \: 60 = 10x \\ \\ \rightarrow \: x = \frac{60}{10} \\ \\ \rightarrow \: x = 6$

Hence,

• Length =x= 6cm

•Breadth= 4x= 4×6= 24 cm
