Step-by-step explanation:
a)i) perimeter= side+side+side+side
perimeter=8.7+8.7+5.4+5.4=28.2cm
ii) area=h×b
area=8.7×5.4=46.98cm²
b)i) perimeter=20.35+20.35+17.84+17.84
perimeter=76.38cm
ii)area=20.35×17.84
area=363.044cm²
c) area of rectangular field=937.125m²
Length=36.75m
i)Breadth=937.125÷36.75=25.5m
ii)perimeter=36.75+36.75+25.5+25.5
perimeter=124.5m
Let the initial population = P
increase in population = 35%
35% of P = 35/100 P = 0.35P
P + 0.35P = 91800
1.35P = 91800
P = 91800/1.35
P = 68,000
Previous population was 68,000
Answer:
They are adjacent.
Step-by-step explanation:
2x + 4x = 90°
6x = 90°
therefore x = 90°/6 = 15°
