Area of triangle = 1/2 x base x height

So, area of triangle = 1/2 x 13 x 6 = 39 meter^2

Answer:

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Step-by-step explanation:

Given:

Consider a rectangle ABCD as shown in the figure below where,

Area (ABCD) = 635 × 7 = 4445

Therefore length and width of a rectangle will be

LENGTH =635 = AB

WIDTH = 7 = AD

To Find:

AE =?

EF = ?

FB = ?

Ar(EFGH)=?

Ar(ABCD) =?

Solution:

We know that area of the rectangle is given by

$\textrm{Area of rectangle}= LENGTH\times WIDTH$

$\textrm{Area of rectangle ABCD}= 635\times 7=4445\ unit^{2}$

Substituting the values we get

$\textrm{Area of rectangle AEHD}= AE\times 7\\\\4200=AE\times 7\\\therefore AE=\dfrac{4200}{7}=600$

Similarly for area rectangle FBCG,

$\textrm{Area of rectangle FBCG}= FB\times 7\\\\35=FB\times 7\\\therefore FB=\dfrac{35}{7}=5$

Now we have

AB = 635,

$AE + EF + FB = 635\\\\600+EF+5=635\\\\EF=635 -605=30\\\therefore EF = 30$

Similarly for area rectangle EFGH,

$\textrm{Area of rectangle EFGH}= EF\times 7\\\\=30\times 7=210\ isunit^{2}$

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

1. Compare the fraction.

denis23 [38]

1. 1/6 < 5/6 - answer A.
2. 4/7 (?) 1/6
First fraction is bigger, to check it, make both fractions to be x/42, so 24/42 > 7/42 - answer A.

Two airplanes leave the same place and fly in opposite directions. The average rate of one plane is 32 miles per hour faster tha

eduard

Answer:

speed of one plane is 50 miles/hour

Speed of other plane is 82 miles/hour

Step-by-step explanation:

Given : Two airplanes leave the same place and fly in opposite directions. The average rate of one plane is 32 miles per hour faster than the other one.

To Find: . Find the rate of each plane if they are 1098 miles apart after 1 1/2 hours

Solution : Let the speed of one plane be x miles per hour

Time = $1\frac{1}{2} =\frac{3}{2} =1.5 hours$

So, distance traveled by one plane in 1.5 hours = speed * time

= 1.5 x

Since we are given that speed of other plane is 32 more than one

So, speed of other plane is x+32 miles per hour

Time = 1.5 hours

So, distance traveled by other plane in 1.5 hours = speed * time

= 1.5 (x+32)

Since they are 1098 miles apart after 1.5 hours

So, $1.5x+1.5(x+32)=1098$

$1.5x+1.5x+48=1098$

$3x+48=1098$

$3x=1050$

$x=\frac{1050}{3}$

$x=50$

So, speed of one plane is 50 miles/hour

Speed of other plane is x+32=50+32 =82 miles/hour
