Answer:
Question 7
Answer : 1200 inches squared
Question: 8
Answer: 84 centimeters squared
Question: 9
Answer: 2304 feet squared
Step-by-step explanation:
1) Q7: Parallelogram
A=BH
base 30 inch X height 40 inch = 1200 inches squared
2) Q8: Rhombus
A=pq
/2
Multiply the two diagonals then divide by 2
Diagonals 14 cent X Diagonal 12 cent divided by 2 = 84 centimeters squared
3) Q9: Trapezoid
A= (B1+B2)H/2
Add the two bases times the height divide by 2
gives you:
2304 feet squared
