In the rectangle ABDF above, C and E are midpoints of sides line ED and line DF, respectively, what fraction of the areas of the

aivan3 [116]

Answer:

Is shaded 5/8 of the area of the rectangle

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of triangle ABC represent 1/4 of the total area

The area of triangle CDE represent 1/8 of the total area

The shaded region is composed by one triangle equal to triangle ABC and three triangles equal to triangle CDE

The area of the shaded region is equal to

$(1/4)(1)+(1/8)(3)=(1/4)+(3/8)=(2/8)+(3/8)=5/8$

therefore

Is shaded 5/8 of the area of the rectangle

A school is designing two rectangular parking lots. The second parking lot is being designed so that its perimeter is 3/4 of per

Nataly [62]

The perimeter of second plot is 180 feet

<em><u>Solution:</u></em>

Given that,

The second parking lot is being designed so that its perimeter is 3/4 of perimeter of the first parking lot

<h3><u>Find the perimeter of first plot:</u></h3>

Perimeter = 2(length + width)

From given figure in question,

length = 40 feet

width = 80 feet

Therefore,

Perimeter = 2(40 + 80)

Perimeter = 2(120) = 240

Thus, we got,

Perimeter of first parking plot = 240 feet

Also, given that,

$\text{Perimeter of second plot }= \frac{3}{4} \times \text{Perimeter of first parking plot}\\\\\text{Perimeter of second plot }= \frac{3}{4} \times 240\\\\\text{Perimeter of second plot }= 180$
