The area of triangle AED is 20 square meters. Find the area of parallelogram ABCD.20 square meters
52 square meters
15 square meters
104 square meters
diagram below.

Answers

Answer 1
Answer: I found the accompanying image of this problem. The triangle is a right triangle.

area of a right triangle = ab/2    where: a and b are the legs
based on the image: a = 5 m
20 square meters = (5m * b) /2
20 sq. m * 2 = 5m * b
40 sq. m / 5m = b
8 m = b 

So the image consists of 2 right triangles with a square in the middle.

Area of a square = a² = (8m)² = 64m²

Total area of the parallelogram = 2 right triangle * 20m² + 1 square *64m²
Total Area = 40m² + 64m²
Total area = 104m² ⇒ 104 square meters.

p/4+3-8p>-2
multiply by 4
p+12-32p>-8
12-31p>-8
add 31p to both sides
12>31p-8
add 8 to both sides
20>31p
divide both sides by 31

A rectangle has an area of 40 square units. The length is 6 units greater than the width.

Answers

Let

x------> the length of the rectangle

y------> the width of the rectangle

A-----> area of the rectangle

we know that

The area of rectangle is equal to

A=x*y\nA=40\ units^(2)

so

40=x*y --------> equation 1

x=6+y --------> equation 2

Substitute equation 2 in equation 1

40=[6+y]*y\n 40=6y+y^(2) \ny^(2) +6y-40=0

using a graph tool-----> to resolve the second order equation

see the attached figure

the solution is

y=4

Find the value of x

x=6+y\n \n x=6+4=10\ units

therefore

the answer is

The length of the rectangle is equal to 10\ units

The width of the rectangle is equal to 4 \ units
possible dimensions:
40 x 1
20 x 2
4 x 10
5 x 8

since 10 is 6 more than 4, the length is 10 and the width is 4

What is the 217th digit after the decimal point in the repeating decimal 0.3456? How can i calculate this?

Answers

Well I think you mean 0.(3456), I will try to explain as simple as I can ;p

First I would divide 217 by 4, because we need to find 217th digit in 4 digit repeating decimal:

217/4=(217)/(4)=54(1)/(4)

54(1)/(4) it means that 3456 will be reapeted 54 times untill 217th digit, and (1)/(4) means that the 217th digit will be the first of those 4 digits in this decimal, so your answer is:
The 217th number after the decimal point in this repeating decimal will be 3
