Question

the side of a square ABCD is 5cm and another pqrs has perimeter is equal to 40 cm find the ratio of the perimeter of ABCD 2 perimeter of pqrs find the ratio of the area of ABCD 2 the area of pqrs​

Answer 1

Perimeter of ABCD= 4×side

4×5

20 cm

ratio of perimeter = 20/40=1/2 =

=1:2

area of ABCD=s×s

5×5=25

p of pqrs= 4×side

40=4×side

side =40/4

=10 cm

area=s×s=10×10=100

ratio=25/100=1/4=

=1:4
