5 m

Step-by-step explanation:

A rectangular field is 15 m long and 10 m wide. Another rectangular field having the same

perimeter has its sides in the ratio 4 : 1. Find the

dimension of the rectangular field.Area on is the surface or region enclosed. 5 m

Answer 2

Step-by-step explanation:

perimeter of first rectangular field = 2 (L + B)

= 2 ( 15 + 10 )

= 2 X 25

= 50 m

since, perimeter of both field are same.

also, let length of another rectangle = 4x and breadth of another rectangle = x

now,. Perimeter = 50

2( L + B ) = 50

(L + B ) = 50 ÷ 2

4x + x = 25

5x = 25

x = 25 ÷ 5

x = 5 m

so length = 4 X 5 = 20 m

breadth = 5 m

Area of another reactangle = L X B

= 20 X 5 = 100 m²
