Answer:
23 cm squared
Step-by-step explanation:
Split the shape into two shapes.
<u>Shape one:</u>
5 x 3 = 15 cm squared
<u>Shape two:</u>
7 - 3 = 4 (length of a side of the second shape)
4 x 2 = 8 cm squared
15 + 8 = 23 cm squared
 
        
             
        
        
        
Subtract 76 on both sides:
2401 - 76 = 76 - 2x - 76 
2325 = -2x
Divide both sides by -2:
-1162.5 = x
