Question

the perimeter of rectangular park is 560m it's breadth is 100m find the length of park ​

Answer 1

Answer:

Answer is 180 m

Step-by-step explanation:

Let the length be x

So,

$2 \times (100 + x) = 560 \\ 100 + x = \frac{560}{2 } \\ 100 + x = 280 \\ x = 280 - 100 \\ x = 18$

Answer 2

Answer:

180m

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

Given, perimeter = 560m, breadth = 100m.

=> 2(l+100) = 560

=> l+100 = 560/2

=> l+100 = 280

=> l = 280-100

=> length = 180m
