Answer 1

Answer:

width = 8 cm

length = 40 cm

Step-by-step explanation:

let's take the width of the rectangle be x

length = 4x + 8

now,

perimeter = 2 × ( length + width )

=》P = 2 × ( 4x + 8 + x )

=》P = 2 × ( 5x + 8 )

=》P = 10x + 16

now, we know perimeter = 96 sq.cm

so,

=》10x + 16 = 96

=》10x = 96 - 16

=》x = 80 ÷ 10

=》x = 8

since, width = x , so width = 8 cm

length = 4x + 8 = (4 × 8) + 8

= 32 + 8 = 40 cm

Answer 2

Answer:

$its \: dimensions \: are \to \\\boxed{w = 17.6cm} \: \boxed{l = 78.4cm}$

Step-by-step explanation:

$if \to l = 4w + 8 \\ but \\ \: perimeter(p )= l + w = 96 \\ 4w + 8 + w = 96 \\ 5w + 8 = 96 \\ 5w = 96 - 8 \\ 5w = 88 \\ w = \frac{88}{8} \\ \boxed{w = 17.6cm} \boxed{l = 78.4cm}$
