A parallelogram has an area of 448 square centimeters and a base length of 16 centimeters what is the height of the parallelogram?

14cm
16cm
12cm
28cm

28cm

Step-by-step explanation:

Area of a parallelogram = base x height

Given area = 448cm^2

Base = 16 cm

Therefore,

448 = 16 x h

Divide both sides by 16

448/16 = 16/16 x h

28 = h

h = 28cm

first do 2y (3y+2+4y+5) then do 3 (3y+2+4y+5)

this gives you 6y^2 + 4y + 8y^2 + 10y + 9y + 6 + 12y +15

after this you add like terms: 6y^2 + 8y^2 = 14y^2

4y + 10y + 9y + 12y = 35y

6 + 15 = 21

put them all together to get your final answer: 14y^2 + 35y + 21
