Answer 1

The unknown length, x, in the smaller quadrilateral is 3 cm

Solution:

Given that,

The proportion can be solved to find the unknown length , x, in the smaller quadrilateral

Given proportion is:

$\frac{x}{1.5} = \frac{9}{4.5}$

We have to find the value of "x"

From given proportion,

$\frac{x}{1.5} = \frac{9}{4.5}$

Cross multiply the numerator of left side fraction with denominator of right side fraction

Multiply the numerator of right side fraction with denominator of left side fraction

Solve for x

$x \times 4.5 = 9 \times 1.5\\\\4.5x = 13.5\\\\x = \frac{13.5}{4.5}\\\\x = 3$

Thus unknown length, x, in the smaller quadrilateral is 3 cm
