Note that sum of triangle interior angles is 180. So,

$(12x+12)+15+(3x+18)=180$

$15x+45=180$

$15x=135$

$x=9$

Since $A=12x+12=12.9+12=120$

And $C=3x+18=3.9+18=45$

jeyben [28]

Answer:

Length of the original rectangle is 2.75 cm

Step-by-step explanation:

The dimensions of the scale drawing of rectangle are 8 cm and 11 cm respectively.

This implies that the width of the rectangle is 8 cm while the length of the rectangle is 11 cm.

The scale factor is given as 4. This means that the dimensions of the original rectangle are 1/4 times the given dimensions.

So the length of the original rectangle = $\frac{1}{4}*11$

= $2.75$
