So to find the perimeter you have to find the length of the diagonal lines. The definition of isosceles means that the shape has two sides of equal length. So you’d solve for te missing length using the Pythagorean theorem. The difference between the top side and the bottom is 10, which means that each side of the 90 degree is 5. So on the bottom it is 5,12,5 for measurements, meaning that the middle is a square with two right triangles.

Solve using the Pythagorean theorem

a^2+b^2=c^2 with This you should get 9.43 (rounded) as your values.

Then just add up the side lengths.

2(9.43)+22+12, which gives a perimeter of 52.87 (rounded)

5^2+8^2=c^2

Answer:

A =136 cm^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h where b1 and b2 are the lengths of the bases and h is the height

A = 1/2( 22+12) *8

A = 1/2 ( 34)*8

A =136 cm^2

There are 7 roses in a vase of 16 flowers. The rest are daisies.

Answer:

(a) 7:9 or 7 to 9 or $\frac{7}{9}$

(b) 9:16 or 9 to 16 or $\frac{9}{16}$

Step-by-step explanation:

The first thing you need to figure out is how many daisies are in the vase. There are 9. So the answer to question a is 7 roses to 9 daisies. The answer to question b is 9 daisies to 26 total flowers in the vase.

I wrote #:# or # to # or $\frac{#}{#}$ #/# because these are all of the ways you can write a ration. I wasn't sure which one you needed.
