Answer:
<em>588 cm²</em>
Step-by-step explanation:
<em>24 × 7 + 30 × 7 + 2(24 × 18) + 18 × 7</em> = 7(24 + 30 + 18) + 2 × 42 = 7 × 72 + 84 = 504 + 84 = <em>588 cm²</em>

Step-by-step explanation:
Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
