Question

8. Find the length of a rectangular playground whose perimeter is 400 m and breadth is 50 m .​

Answer 1

Answer:

heya frnd! hence, length of the rectangular playground is 150m.

Answer 2

Step-by-step explanation:

let the length of a rectangular playground be x m.

then, perimeter of rectangular playground = 400 m ( given )

but, perimeter of rectangle = 2(length + breadth)

so, 400 = 2(x + 50)

=> 400 = 2x + 100

=> 2x = 400 - 100

=> 2x = 300

so, x = 150

hence, the length of a rectangular playground is 150 m.
