Question

find the length of a rectangular garden which has area of 18 sq m and breath 12 m​

Answer 1

Answer:

1.5

Step-by-step explanation:

l*b=area

L*12=18

L=18/12

L=1.5

Answer 2

$\sf \large \underbrace{ \underline{Correct \: Question}}$

Find the breadth of rectangular garden which has area of 18 sq m and length 12m.

$\sf \large \underbrace{ \underline{Understanding \: the \: Question}}$

As area and length of rectangle are given we can easily find the breadth of rectangular garden by applying formula of area of rectangle.

So let's start!

★Area of rectangle=Length×breadth

$\sf : \implies \: \: \: 18cm²=12×breadth$

$\large\sf : \implies \: \: \:\frac{ 18cm²}{12}=breadth$

$\sf : \implies \: \: \: 1.5cm=breadth$

So breadth of rectangle is 1.5cm
