Question

A rectangle is 20 cm long and 8 cm wide. A square with the same perimeter as this rectangle will have an area of

Answer 1

length of rectangle = 20cm
breadth of rectangle = 8cm
perimeter = 2×(length+breadth)
perimeter = 2×(20+8)
perimeter = 2 ×28
perimeter of rectangle = 56cm
perimeter of rectangle = perimeter of square
56 = 4× side of square
side of square = 56/4
side of square = 14cm
area of square = (side)^2
area = 14×14

area of square = 196cm square

Answer 2

Answer:

Step-by-step explanation:

Rectangle:-

Length=20cm

Width=8cm

Perimeter=2*(l+b)

=2*(20+8)

=2*28

=56cm

Now,

Square's perimeter=56cm

Each side of the square measures=56/4

=14cm

Area of square=s*s

=14*14

=196 square cm
