Question

the perimeter of yes wire field and rectangular field are the same if one side of the rectangular field is 18 metre and one side off the square field it is 15 metre find
I) the area of the rectangular field
ii) the total area of both the fields​

Answer 1

given

• perimeter of rectangle= perimeter of square
• one side of rectangle is 18 cm
• side of square is 15 cm

To find-

• I) the area of the rectangular field
• ii) the total area of both the fields

solutions

area of rec = area of square

2(l+b)=4a

2(18+b)=4*15

2(18+b)=60

(18+b)=30

b=30-18

b=12 cm

hence the width of rectangle is 12 cm

1) area of rectangle ???

area of rec -l*b

where

• length is 18 cm
• width is 12 cm

put value

18* 12

=216 square cm

2) total area of both field

as we know area of rectangular field is 216 square cm

area of square field is

side*side

15*15

=225 square cm

total area

=area of square field +area of rectangle field

=216 +225

=441 square cm
