Question

the perimeter of a rectangle field is 320m,if the length in 100m,find it's breadth and area​

Answer 1

Answer:

breadth = 540 m

area = 54000 m²

Step-by-step explanation:

Perimeter = 2(length + breadth)

320 = 2(100 + breadth)

640 = 100 + breadth

breadth = 540 m

area of rectangle = length * breadth = 100 * 540 = 54000 m²

Answer 2

Answer:

perimeter of a rectangle = 320

2(l+b) = 320

2(100+b) = 320

200+2b = 320

2b = 320-200

2b = 120

b = 120/2

b = 60

area of a rectangle = l×b

= 100×60

= 6000m²

Area = 6000m²
