If the area of a triangle with a base measuring 22 feet is 93.5 square feet, find its height.

Answers

Answer:

height = 8.5 feet

Step-by-step explanation:

Area of a triangle formula:

a=1/2bh

substitute what's given

93.5 = (1/2)22h

93.5=11h

divide both sides by 11 to isolate h

h=8.5 ft

Find the area of the polygon.

Answers

Answer: use formulas for area of square/triangle

Step-by-step explanation:

1st one is a rhombus so use A= BH

which is 5x4 = 20

2nd one is a kite

i assume you have not learnt the formula for kites so u can use triangles (A=1/2BH)

triangle CBA: 1/2 x (6+6)(2) = 12

triangle ACD: 1/2 x (6+6)(10)= 60

area = 12 + 60 = 72

green/first polygon:

Four equal triangles inside a polygon, so we have to find an area of one triangle and multiply that area with four since there are four triangles in total.

base is 5, height is 4. area of triangle formula: A = (bh) / 2 = (5x4) / 2 = 20 / 2 = 1010 x 4 = 40 (b/c there are four equal triangles)40 square units is the area of green/second polygon

________________________________________________________

teal/second polygon:

Two equal triangles and another two (different) equal triangles, so we have to find an area of a smaller triangle and multiply that area with two since there are two equal smaller triangles.

Then we have to find an area of a larger triangle and multiply that area with two since there are two larger equal triangles.

(smaller triangle)base is 6, height is 2. area of triangle formula: A = (bh) / 2 = (6x2) / 2 = 12 / 2 = 66 x 2 = 12 (b/c there are two equal smaller triangles)12  square units of the area of two equal smaller triangles (so we're not done yet!)

------------------------------------------------------------

(larger triangle)base is 10, height is 6. area of triangle formula: A = (bh) / 2 = (10x6) / 2 = 60 / 2 = 3030 x 2 = 60 (b/c there are two equal larger triangles)60 square units of the area of two equal larger triangles

12 + 60 = 72

72 square units is the area of teal/second polygon.

Time : liters

[tex]\left[\begin{array}{ccc}0&16\\1&20\\2&24\\3&28\\4&32\\5&36\\6&40\end{array}\right][/tex]

We can see using the table that at 5 minutes, there would be 36 liters of water in the tank. Since Kala is going to keep filling the tank until there is more than 36 liters, the inequality would be t > 5.
