please help me answer this

Answer 1

A) it will be
Area-lb =9*3=27mm.sq
Perimeter- 2l+2b =2*9+2*3=24mm

B) area -a*a=13*13=169inc
Perimeter- 4*side=4*13=56 Inc

C)

Answer 2

Answer:

a) Area = 27 sq mm

Perimeter = 24 mm

             

b) Area = 169 sq in.

Perimeter = 52 in.

c) Area = 15 sq cm

Perimeter = 16 cm

d) Area = 729 sq m

Perimeter = 108 m

e) Area = 40 sq ft

Perimeter = 26 ft

Step-by-step explanation:

Because area = Length x Breadth, and Perimeter = 2 x (Length + Breadth),

a) Area = 3 x 9 mm = 27 sq mm

Perimeter = 2 x (3+9 mm) = 24 mm

b) Area = 13 x 13 in = 169 sq in.

Perimeter = 2 x (13 + 13) = 52 in.

c) Area = 5 x 3 cm = 15 sq cm

Perimeter = 2 x (5 + 3) = 16 cm

d) Area = 27 x 27 m = 729 sq m

Perimeter = 2 x (27 + 27) = 108 m

e) Area = 8 x 5 ft = 40 sq ft

Perimeter =2 x (8 + 5) = 26 ft

I hope it helps!
