Question

length of a rectangular field is 90 M and side of square field is 60 M if area of the rectangular field is equal to the area of square field find the perimeter of rectangle find

Answer 1

let breadth of field be x m


according to question

90x=60×60
x=40


so breadth is 40 m

so perimeter of field =2 (40+90).
=260m

Answer 2

Area of square is side × side
60× 60
3600
Area of rectangle is 3600m^2
3600 = l× b
3600 =90×b
3600÷90 =b
40=b
Perimeter of rectangle = 2(l+b)
2(90+40)
2×130
260m
