The vegetable patch is a trapezoid.

The formula for a trapezoid is A=[(a+b)/2]*h

we can substitute to get A=[(5+7)/2]*10

we solve this and get 60 meters







solving for the flower bed, we use (b*h)/2 since it is a triangle

substituting we get (3*8)/2

this simplified is 12







we add 12 and 240 to get a area of the flower bed and vegetable garden to be 72 meters







we calculate the total area by multiplying lw. we substitute to get 10(14) and get a total area of 140







we subtract 72 from 140 to get an answer of 68 sq m

A person spends 1/5 of his salary on rent, 3/7 on food, 1/3 on other expenses and saves the rest. If she earns $21,000 per month
sukhopar [10]

Answer:

$9600 saving / year

Step-by-step explanation:

1/5 of $21000 = 21000 / 5 = $4200 / month on rent

3/7 of $21000 = (21000 / 7) x 3 = $9000 / month on food (shocking right :) food is expensive)

1/3 of $21000 = 21000 / 3 = $7000 on other expenses / month

total savings/month = salary/month - rent/month - food/month - other expenses/month

total savings/month = 21000 - 4200 - 9000 - 7000

total savings/month = $800

<u><em>BUT</em></u> the question asks for savings per year. therefore, we must multiply the savings per month by total months per year (12)

800 x 12 = $9600

the person's total savings per year, with a salary of $21000 per month, is equal to $9600 per year
