Question

find the area of a square whose perimeter is equal to the perimeter of a rectangle whose length and breadth is 30 and 20 CM respectively​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of square = perimeter of rectangle

4side = 2(l+b)

Let side = x

4x = 2(30+20)

4x = 2×50

4x=100

X=100/4=25

Sides of square = 25cm

Area of square = side ²

= (25)² = 625cm²

Answer 2

Given

Length=30cm

Breadth=20cm

perimeter of the rectangle=2(l+b)

=2(30+20)

=2(50)

=100 cm

Given that,

Perimeter of a rectangle=perimeter of

square

perimeter of a square=100cm

we can replace the formula,

4*side=100cm

side=100/4cm

side=25cm

then,

Area of square= (side)^2

=(25)^2= 625 cm^2

Hope it helps
