Question

the length of a rectangular garden is four times it's breadth if the breadth of the field 9m.find the perimeter of the field​

Answer 1

$\infty \huge \bold \red{ \alpha } \huge \mathfrak \pink{ nswer} \gamma$

The perimeter of the field = 90 m

Step-by-step explanation:

Given that:

Breadth of the rectangle = 9 m

Length is four times of Breadth i.e., 4 × 9 = 36 m

To find:

Perimeter of the field.

Formula to find the perimeter of a rectangle:

Perimeter of a rectangle = 2(L + B) unit.

Here,

Length is denoted by L.

Breadth is denoted by B.

Finding the perimeter of field which is in rectangular in shape:

➼ Perimeter of field = 2(36 + 9) m

➼ Perimeter of field = 2 × 45 m

➼ Perimeter of field = 90 m

Answer 2

The perimeter of the field = 90 m

Step-by-step explanation:

Given that:

Breadth of the rectangle = 9 m

Length is four times of Breadth i.e., 4 × 9 = 36 m
