Question

The areas of a square and a rectangle are equal. If length and breadth of a rectangle are x and respectively, find the perimeter of a square.​

Answer 1

Answer:

let the breadth of rectangle be x.

the breadth of rectangle be x. area of square = area of rectangle

the breadth of rectangle be x. area of square = area of rectangle 18×18=x×36

the breadth of rectangle be x. area of square = area of rectangle 18×18=x×36 x=9

the breadth of rectangle be x. area of square = area of rectangle 18×18=x×36 x=9 perimeter=2(l+b)

the breadth of rectangle be x. area of square = area of rectangle 18×18=x×36 x=9 perimeter=2(l+b) =2(9+36)

the breadth of rectangle be x. area of square = area of rectangle 18×18=x×36 x=9 perimeter=2(l+b) =2(9+36) =90 cm
