The figure shows trapezoid ABCD on a coordinate plane.
docker41 [41]

Answer:

121 unit^2.

Step-by-step explanation:

The area = height/2 * ( sum of the opposite parallel  lines)

= h/2(BC + AD

h = BF = 14 - 3 = 11 units.

BC   = 13 - 5 = 8 units.

AD = 16 - 2 = 14 units.

Area = (11/2)(8 + 14)

= 5.5 * 22

= 121 unit^2.

Trapezoid QRST has two right angles. A 5in. altitude can be drawn dividing QRST into a rectangle and an isosceles right triangle
iVinArrow [24]
The area of the trapezoid is 57.5 square inches.

If you draw out the description, you will see that your trapezoid can be divided into a rectangle that is 9 x 5 and an isosceles right triangle with a base of 5 and height of 5. 

Just find the areas of both and add them together.

Rectangle:
5 x 9 = 45

Triangle:
0.5 x 5 x 5 = 12.5

45 + 12.5 = 57.5

Anni [7]

Ronna collected 12\frac{3}{4} bags of clothes

Step-by-step explanation:

Tristan and Ronna are collecting clothes for a clothing drive

  • Ronna collected 3 times as many clothes as Tristan
  • Tristan collected 4\frac{1}{4} bags

We need to find how many bags of clothes  Ronna collected

∵ Ronna collected 3 times as many clothes as Tristan did

- That means Ronna collected 3 × the amount that Tristan did

∵ Tristan collected 4\frac{1}{4} bags

- Multiply the amount of Tristan by 3 to find the amount of Ronna

∴ Ronna collected = 3 × 4\frac{1}{4}

Change the mixed number to improper fraction

∵ 4\frac{1}{4} = \frac{(4*4)+1}{4}=\frac{17}{4}

∴ Ronna collected = 3 × \frac{17}{4}

∴ Ronna collected = \frac{51}{4}

Change the improper fraction to mixed number by divide 51 by 4

∵ 51 ÷ 4 = 12 and reminder 3 (4 × 12 = 48 and 51 - 48 = 3)

∴ \frac{51}{3}=12\frac{3}{4}

∴ Ronna collected = 12\frac{3}{4} bags of clothes

Ronna collected 12\frac{3}{4} bags of clothes
