Question

The perimeter of a rectangular field 80m long is 240 cm. Find the area of the fields in ares

Answer 1

Answer:

Perimeter of Field= Length×Breadth

240m = 80m × x

x = 240/80

= 3m

Hence,The breadth is 3m

Step-by-step explanation:

Answer 2

(((The Length is 80 'cm' not 'm')))

Answer:

Length[l] = 80cm$\frac{x}{y} x = 240 y = 2$

Perimeter = 240cm

Breadth[b] = ?

Area = ?

Perimeter = 2[lb]

Let b  be 'x'

ie,

2[l+b] = 240cm

=> 2*[80+x] = 240

=> 80+x = $\frac{240}{2}$

=> x =  120-80

=> x = 40

The breadth is 40 cm

The area is 80 x 40

= 3200$cm^{2}$
