Question

Perimeter=300 m breadth=15 m find the lenght

Answer 1

Answer:

Length = 135m

Step-by-step explanation:

P = 2(l+b)

2 (l+15)=300

2l + 30 = 300

2l = 300-30

2l = 270

l = 270/2

l = 135m

Answer 2

Answer:

given

perimeter = 300m

breadth = 15m

length = ?

perimeter of a rectangle = 2(l+ b)

300 = 2 ( l + 15)

300 = 2l + 2×15

300 = 2l + 30

300 - 30 = 2l

270 = 2l

l = 270/2 = 135

hence length is 135 m.
