Answer:
<h2> 18.3</h2>
Step-by-step explanation:
from cosines theorem:
t² = 11² + 14² - 2•11•14•cos87°
t² = 121 + 196 + 308•0.05236
t² = 333.12688
t = √333.12688
t = 18.2517... ≈ 18.3
Answer:
A = 13.23 m²
Step-by-step explanation:
A = bh
Where,
A = area of the parallelogram
b = base of the parallelogram
h = height of the parallelogram
From the question, assume
b = 2.1 m
h = 6.3 m
A = bh
= 2.1 m × 6.3 m
= 13.23 m²
A = 13.23 m²
