A rectangle and a square are of equal area. If the length and the perimeter of a rectangle are 25 cm and 58 cm respectively, then find the perimeter and area of the square?

Answer» Let thelength of rectangle =l=25cm
Breath=bcm
Side of square=acm
Area of square=are of rectangle
`a^2=lb-(1)`
Perimeter=2(l+b)=58
l+b=29
b=4 cm
Area of square`(a^2)=lb=25*4=100 cm^2`
`a=10 cm`
Perimeter of square=4a
`4*10=10 cm`.
