Answer:
The area is 452cm
Step-by-step explanation:
For the big square we have to multiply 15*18 and that is the area so-
15*18=270
Next we multiply 13 and 14
13*14=182
And now we add 270 and 182 to get the total area
270+182=452
Im not quite sure but i think the unit rate is 150. Hope this helps!!
