Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
Answer:
The deer population decreased. The producers increased. So the number of different species increased.
Step-by-step explanation:
wolves are reintroduced ---> deer population decreases --> producer population begins to increase --> other species numbers increase as well
Step-by-step explanation:
Area of trapezium = ½×(sum of parallel side)×height
=½×(7.9+10.8)×6.2
=½×18.7×6.2
=18.7×3.1. [½×6.2=3.1]
=57.97
