A rectangle has an area of 24m squared. Another triangle has 4 less than 2 times the area of the rectangle. If the height of the triangle is 11 m. What is the base of the triangle?
Calculate triangle area:
a = 2r - 4
= 2 x 24 - 4
= 44 m squared
Use area of triangle formula:
a = b x h /2
44 = b x 11 /2
8 = b
Nina and Betty rent an apartment near Downtown. They paid $11,460 towards rent for the first 3 months. Rent prices went down for the rest of that year. By the end of the year, they had paid a total of $34,320. How much cheaper was it per month to rent after prices went down?
Rent per month for first 3 months:
11460 ÷ f = r
11460 ÷ 3 = $3820
Rent left for the last 9 months:
34320 = 11460 + L
= 22860
Rent per month:
22860 ÷ m = t
22860 ÷ 9 = 2540
Difference in costs:
d = r - p
= 3280 - 2540
= 1280
After the rent prices went down, it was $1,280 cheaper per month to rent the apartment.
The length (L) of a rectangle is 2 more cm than its width (W). The perimeter of the rectangle is 44 cm. What is it's length and width?
Hint: You can combine variables (ex. n + n = 2n)
p = L + L + W + W
length:
2 + w
p = (2 + w) + (2 + w) + w + w
44 = 4w + 4
10cm = w
L = 2 + w
L = 2 + 10
L = 12cm
ANSWER: Length is 12cm and width is 10cm
