Question

the length and breadth of a rectangular field are 4 whole 1/5 m and 1 whole 3/7 m , respectively. Find the area of the rectangular field .

Answer 1

Given:

The length of the rectangular field = (l) = $4\dfrac{1}{5}\ m$

And

The breadth of the rectangular field = (b) = $1\dfrac{3}{7}\ m$

To be found:

Area of the rectangular field

The formula for finding the area of a rectangle

$\pink{\boxed{\sf{length \times breadth\ unit^2}}}$

Length (l) = $\bf 4\dfrac{1}{5} = 4 \times 5 +1 = 20+1 = \dfrac{21}{5} m$

And

Breadth (b) = $\bf 1\dfrac{3}{7} = 7 \times 1+3 = \dfrac{10}{7}m$

Now,

Area of the rectangular field

$\bf = \dfrac{^3\not{21}}{\not{5}^1} \times \dfrac{^2 \not{10}}{\not{7}^1} \\ \\ \\ = 3 \times 2\\ \\ \\ = 6m^2$

Hence,

The area of the rectangular field is $\bf 6m^2$.
