Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²
Answer:
yes

Step-by-step explanation:
Let t represent the number of trees Jacob needs to trim. He wants ...
50(45) +120t ≥ 4500
