It already is in unit form.
Ok so the area of the triangle on the left would be:
A = (1/2)*bh
A = (1/2)*30*78
= 15*78
= 1170 ft^2
Now since the shape is a parallelogram, the two triangles should have the same area (imagine taking off the triangle on the left and sticking it next to the triangle on the right - this will form a rectangle made up of the two triangles)
So area of the garden = 1170*2 = 2340 ft^2
C I guess sorry if I get you a low score
Given the percentage taken off and the reduced price, the original price of the item is $142.
<h3>What was the original price of the item?</h3>
Given the data in the question;
- Percentage off the item = 20%
- Reduced price of the item = $113.60
- Original price of the item = ?
The original price of the item is at 100%, if the 20% is taken off. The price is now at 80%.
Hence 80% of the original price will give the reduced price.
Let the original price be represented by x
80% × x = $113.60
We solve for x
80/100 × x = $113.60
80x/100 = $113.60
Cross multiply
80x = $11360
x = $11360/80
x = $142
Given the percentage taken off and the reduced price, the original price of the item is $142.
