Question

12. A rectangle and a square have the same
perimeter (Fig. 6,10).
(a) The area of the rectangle is
(b) The area of the square is
Fig. 6.10​

Answer 1

Answer:

(a) Area of rectangle is 12cm

(b) Area of square is 16cm

Step-by-step explanation:

Perimeter of rectangle =2×(2+6)

=2×8

=16cm

Perimeter of square is also 16 so one side of square is 4cm

Area of square =(4×4)cm

=16cmsq

Area of rectangle =(2×6)cm

=12cmsq

Answer 2

Answer:

area of rectangle=12cm^2

area of the square =16cm^2

Step-by-step explanation:

perimeter of the rectangle =2(l+b)

=2(2+6)

=2(8)

=16 cm

given that

perimeter of rectangle= perimeter of square

16 cm. = 4a

a= 16/4

a=4

side of square = 4cm

area of square =a^2

=4^2

=16 cm^2

Area of rectangle = l×b

=2×6

= 12 cm^2
