Question

The walls around a playground measure 410m.If one wall along the length of the playground is 80m long,what is the length of the wall aling 8ts breadth?Whar is the area of the playground?

Answer 1

Answer:

length= 125 m

area = 10000 m^2

Step-by-step explanation:

If the  walls around a playground measure 410m,

then the perimeter of the playground is 410 m.

If the length of the playground is 80 m long, then its breadth can be found as;

P=2(L+W)

410=2(80 + W)

410= 160 + 2W

2W= 410-160

2W= 250

W= 125 m

Therefore the length of the playground is 125 m long.

The area of the playground can be computed as

Area= Length x Width

       = 125 x 80

       = 10000 m^2
