Question

please can anyone help me very urgent ​

Answer 1

1) A: Perimeter

B: Side

C: Area

D: Side × Side

2) area of square = 16

$s {}^{2} = 16$

$s = \sqrt{16}$

$s = 4$

Hence side = 4 cm .

3) a) Perimeter of Equilateral Triangle = 3 × side

= 3 × 5

= 15 cm

b) Perimeter of Rectangle

= 2(l+b)

= 2(5+4)

= 2× 9

= 18 cm

c) Perimeter of Square = 4 × side

= 4 × 15 cm

= 60 cm

4) Perimeter of Rectangle

= 2(l+b)

=2(175 + 125)

= 2× 300

= 600 m

Cost of fencing = 12 per metre

= 12 × 600

= 7,200 rupees

I Hope it will help you

Thank s..
