Question

The perimeter of a rectangular garden is 420 m and its length is 120 m. What is the breath?

Answer 1

Answer:

90m

Step-by-step explanation:

As we know formula of the perimeter of a rectangle = 2(length+breadth)

Now we need to substitute the values in place as given so

420 = 2(120+breadth)

=> 420/2 =120+breadth

=> 210 - 120 = breadth

=> 90 = breadth

So breadth = 90m

Please mark as brainliest.

Answer 2

The breadth of the Rectangle is 90m

Explanation:

Given:

1. The perimeter of a rectangular garden is 420 m

2. Length is 120 m.

To find:

The breadth

Formula:

The Perimeter of a rectangle (P)= 2(l+b)

Substitute the given values in the formula

==> P = 2(l+b)

==> P = 420m

==> l = 120m

==> 420 =2(120+b)

==> 420 = 2(120)+2b

==> 420 = 240+2b

==> 420-240 =2b

==> 180 = 2b

==> 2b = 180

==> b = 180/2

==> b = 90 m

The breadth of the Rectangle is 90m
