Question

the perimeter of a square is equal to that of a rectangle of length 15 cm and breadth 13 cm find its area​

Answer 1

perimeter of the rectangle = 2× ( l + b )
= 2 × 15 × 13
= 56 m sq.
perimeter of square = 4 × side
side = 56/ 4
= 14 m
area = 14 × 14
= 196 m sq
please say me more thanx and mark me as brainliest dear

Answer 2

perimeter of square = perimeter of rectangle

so, perimeter of rectangle = 2(15+13)

= 56cm

perimeter of square = 4a

56 = 4a

a= 56/4

a = 14

area of the square = a²

= 14²

= 196cm²

hope it helps you
