Question

8. Find the leagth of a rectangular field, if its area is 4125 m2 and the breadth is 55m Also find its perimeter​

Answer 1

GIVEN that

Breadth of a rectangular field = 55m

Area of rectangular field = 4125 sq.m

To Find

Length of the rectangular field

Solution:-)

Let

length of rectangular field = l

Breadth of rectangular field = b

Area ofrectangular feild = A

As Area of rectangle is given by

$Area = l \times b$

Here

$4125 = l \times 55 \\ \\ l = \frac{4125}{55} \\ \\ \red{ \boxed{\boxed{ l = 75m}}}$

Now perimeter of rectangle is given by

$P = 2(l + b)$

Here

$P= 2(75 + 55) \\ \\ = 2 \times 130 \\ \\ \red{ \boxed{\boxed{ P = 260m}}}$

Answer 2

$Area = l \times b$

Here

$4125 = l \times 55 \\ \\ l = \frac{4125}{55} \\ \\ { \boxed{\boxed{ l = 75m}}}$

Perimeter of rectangle is

$Perimeter = 2(l + b)$

Here

$P= 2(75 + 55) \\ \\ = 2 \times 130 \\ \\ { \boxed{\boxed{ Perimeter = 260m}}}$
