Question

the area of a rectangular lawn is 255 m. if the length is 15 M find its perimetre

Answer 1

Answer: 64m

Step-by-step explanation:

Area = length × breadth

255 = 15 × breadth

Breadth = 255/15

= 17 m

Perimeter = 2(length + breadth)

= 2(15+17)

= 2(32)

= 64 m

Answer 2

Answer:

Step-by-step explanation:

Length of lawn =15m (given)

Area of lawn =255m²

lb = 255

15*b= 255

b=255/15

Therefore , breadth of the lawn = 17m

Now,

Perimeter of the lawn= 2(l+b)

=2(15+17)

= 2* 32

=64 m
