Answer:
666
Step-by-step explanation:
surface area of triangle:
1/2 mm x 10mm x 12mm
=60mm²
60mm² x 2 = 120mm²
surface area of rectangle:
13mm x 14mm
= 182mm²
182 mm² x 3
= 546mm²
total surface area:
120mm² + 546mm²
=666mm²
Slope is positive
I noticed a pattern:
3 * 2 + 6 = 12 and 2 * 2 + 5 = 9
This means that a*b = 2a + b.
16!
4 x 3 = 12 + 4 = 16
