Find the area of the parallelogram

slava [35]

Answer:

A = 864 cm

Step-by-step explanation:

Since the parallelogram looks like a trapezoid, I'm going to use that area formula.

The area of a trapezoid can be found with A = (a + b) h/2. So, substitute in the given values. A = (9 x 24) 8/2. A = 216 x 8/2. A = 864.

The ratio of the measures of the three sides of a triangle is 1/4:1/3:1/6 and its perimeter is 31.4 centimetres find the length

lina2011 [118]

Given:

The ratio of the measures of the three sides of a triangle is $\dfrac{1}{4}:\dfrac{1}{3}:\dfrac{1}{6}$ .

Its perimeter is 31.4 centimeters

To find:

The shortest side of the triangle.

Solution:

Let the measures of the three sides of a triangle are $\dfrac{1}{4}x,\dfrac{1}{3}x,\dfrac{1}{6}x$ respectively (in cm).

Its perimeter is 31.4 centimeters.

$\dfrac{1}{4}x+\dfrac{1}{3}x+\dfrac{1}{6}x=31.4$

$\dfrac{3x+4x+2x}{12}=31.4$

$\dfrac{9x}{12}=31.4$

$\dfrac{3x}{4}=31.4$

On further simplification, we get

$3x=4\times 31.4$

$3x=125.6$

Divide both sides by 3.

$x=\dfrac{125.6}{3}$

$x=41.867$

Now, the sides of triangle are

$\dfrac{1}{4}(41.867)=10.467$

$\dfrac{1}{3}(41.867)=13.956$

$\dfrac{1}{6}(41.867)=6.978$

Therefore, the length of the shortest side is 6.978 cm.

a flower bed has the shape of a rectangle 5 yards long and 4 yards wide what is its area in square feet

Over [174]

Area of a rectangle = length times width.

Here, the area is (5 yd)(4 yd) = 20 yd^2. We must convert this into ft^2:

20 yd^2 3 ft

------------ * { ----------- }^2

1 1 yd

The comes out to (20)(3)^9, or 180 ft^3, the area in square feet.
