Question

the area of a rectangle lawn is 255^2m.if it's length is 15m, find its perimeter

Answer 1

Area of rectangle = 255m²

Length = 15m

Let the breadth be ' b '

Area = l × b

255 = 15 × b

$b = \frac{255}{15}$
b =17

Breadth = 17m


Perimeter = 2( length + breadth )

= 2( 15 + 17)m

= 2( 32)m

= 64m

Thus ,

the perimeter is 64 metres

Answer 2

Area of rectangle = length × breadth

255 = 15 × breadth

Breadth = 255/15 = 17 m

Perimeter of rectangle = 2(length + breadth)

Perimeter of rectangle = 2(15 + 17)

Perimeter of rectangle = 2 × 32 = 64 m
