Question

please answer my question I will mark brainliest please​

Answer 1

Answer:

a) L = 4m

so, W = 4×2m = 8 m

Perimeter = 2(l+b)

= 2(4+8)

= 8 + 16

= 24 m

b) 2(x+x^2)

Step-by-step explanation:

I hope this will help you but I am not sure about the b part

Answer 2

Answer:

a) perimeter is 24m

b) perimeter=2*(2x)+2x

Step-by-step explanation:

a)width=2*length

=2*4m

=8m

perimeter=2*(width + length)

=2*(8m + 4m)

=2*12m

=24m

b)width=2*length

=2*x

=2x

perimeter=2*(2x(width))+2x(length)
