Question

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
dimensions of the rectangular field.​

Answer 1

length 20m

breadth 5m

Step-by-step explanation:

perimeter of field 1=2(15+10)

=2×25

=50m

perimeter of field 2 = 50m

2(4x + 1x ) = 50

2×5x =50

10x=50

x=5

length = 4×5

=20m

bredth = 5m

Answer 2

Answer:

area of the field = 15 x 10 = 150

B/c

sum of the ratio terms = 4+1 = 5

length of the rectangle = 4/5 x 150 = 120

breadth of the rectangle = 1/5 x 150 = 30

Therefore area of the other rectangle = 120 x 30 sq.m = 360 sq m
