Answer:
100
Step-by-step explanation:
sum the parts of the ratio, 4 + 5 + 1 = 10 parts
Fiona gets 40 sweets which is 4 parts of the ratio
Divide Fiona's share by 4 to find the value of one part of the ratio
40 ÷ 4 = 10 ← 1 part of the ratio
The total number of sweets is 10 parts , thus
number of sweets in total = 10 × 10 = 100
The best way to do this is to set up a proportion
30 20
---- = -----
0.5 x
then cross multiply and divide
20 × 0.5 = 10/30=1/3

Answer:
100 m^2.
Step-by-step explanation:
The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.
Here we have Area = (1/2 * 10) ( 8 + 12)
= 5 * 20
= 100 m^2.
