Answer 1

13. 204.49 cm²
14. 15 cm²
15. 36 cm²

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:

`A = (hb)/(2)` or
`A = (1)/(2)hb` 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
