Question

find the length of rectangle plot ao land whose perimetre is 150m and breadth is 30 m​

Answer 1

The length of the Rectangle is 45m

Explanation:

Given:

1. Perimeter of Rectangle is 150m

2. Breadth of Rectangle is 30 m​

To find:

The length of rectangle

Formula:

The perimeter of Rectangle = 2(l+b)

Substitute the values in the formula

==> Perimeter(P) =2(l+b)

==> Perimeter of Rectangle is 150m

==> 150 = 2(l+b)

==> Breadth of Rectangle is 30 m​

==> 150 = 2(l+30)

==> 150 = 2l+60

==> 150 = 2l+60

==> 150-60 = 2l

==> 90 = 2l

==> 2l = 90

==> l = 90/2

==> l = 45 m

The length of the Rectangle is 45m

Answer 2

Answer:

Length = 45m

Step-by-step explanation:

Perimeter of rectangle = 150m

Breadth = 30m

Length = ?

Formula of perimeter of rectangle = 2(l+b) = 150

=L+L+b+b = 150

= 2L+60 = 150

= 2L = 150-60

= L = 90/2

= L = 45
