Answer:
13. 204.49 cm²
14. 15 cm²
15. 36 cm²
Step-by-step explanation:
Area of a square is:
A = a² where a is the side length
A = 14.3² cm
A = 204.49 cm²
Area of a triangle is:
[tex]A = \frac{hb}{2}[/tex] or [tex]A = \frac{1}{2}hb[/tex] where h is the vertical height and b is the base length
A = (5×6)÷2
A = 30÷2
A = 15
Area of a rectangle is:
A = L×W where l is the length and w is the width
A = 8×4.5
A = 36
