Please solve both with explanation

Step-by-step explanation:

area of rectangle=length*width

=17 cm*9 cm

=1323 cm^2

perimeter of rectangle=2(l+w)

=2(17+9)

=2*26

=52 cm

area of square=l^2

=12^2

=144 m^2

perimeter of sqaure=4l

=4*12

=48 m

see explanation

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = lb ( l is length, b is breadth )

The perimeter (P) is the sum of the 4 sides

(a)

A = 9 × 17 = 153 cm²

Since opposite sides are congruent, then

P = 2(9 + 17)

  = 2 × 26

  = 52 cm

(b)

A =  12 × 12 = 144 m²

P = 4 × 12 = 48 m

answer: the answer is 23
