In order to prove that this quadrilateral is a parallelogram, we need to get the opposite sides to be parallel.

The answer would be D because it shows 2 triangles to be equal. If they are equal then they must have corresponding sides.

A rectangular patio has a length of 12 1/2 feet and an area of 103 1/8 square feet. What is the width of the patio?

Rina8888 [55]

Length of the rectangular patio = 12 1/2 feet
      = 25/2 feet
Area of the rectangular patio = 103 1/8 square feet
   = 825/8 square feet
Let us assume the width of the rectangular patio = x feet
Then
Area of the rectangular patio = Length * Width
825/8 = (25/2) * x
25x/2 = 825/8
25x = (825 * 2)/8 feet
25x = 825/4 feet
x = 825/(4 * 25) feet
   = 33/4 feet
   = 8 1/4 feet
So the width of the rectangular patio is 8 1/4 feet. I hope the procedure is clear enough for you to understand.

If you cut a 35 inch long stick in two pieces in the ratio 2:3, how long would each part be?

Aliun [14]

Answer:

14 : 21

Step-by-step explanation:

---> 2:3 ----> 2+3=5

---> Stick's length = 35 inches

For the first portion

2/5 x 35

2/1 x 7

= 14 inches

For the second portion

3/5 x 35

3/1 x 7

= 21 inches

To confirm: 14 + 21 = 35 inches

14 : 21

Divide both by 7

2 : 3
