Consider parallelogram ABCD, whose area is 162 sq. feet. If side AD equals 11 feet and the height DE equals 9 feet, find the per
allochka39001 [22]

Answer:

The perimeter of a parallelogram = 58 ft

Step-by-step explanation:

A parallelogram is a quadrilateral with opposite sides parallel and equal in length. Opposite angles are also equal.

Area of parallelogram = base × height

Area = 162 ft²

area = bh

b = ?

h = 9 ft

162 = 9b

divide both sides by 9

b = 162/9

b = 18 ft

The perimeter of a parallelogram = 2(b + s)

where

b = base

s = the other sides

The perimeter of the parallelogram = 2(b + s)

The perimeter of the parallelogram = 2(18 + 11)

The perimeter of the parallelogram = 2(29)

The perimeter of the parallelogram = 58 ft

The lengths of the sides of a square are 5 cm. find the length of the diagonal
jenyasd209 [6]

Answer:

square root (50) = 7.071

Step-by-step explanation:

Using Pthagoras' theorem, the diagonal length is \sqrt{x} ax^{2} +bx^{2}.

Therefore, the diagonal length is the square root of 5^2+5^2,

= \sqrt{x} 25+25

= \sqrt{x} 50

= 7.071

What is the equation in point-slope form of the line passing through (−2, 1) and (4, 13)
Sonja [21]

Answer:

y = 2x + 5

Step-by-step explanation:

We have two points,

(-2,1) and

(4,13)

from which we can find the slope, m, where

m = (13-1)/(4--2) = 12/6 = 2

take any of the two points to form the point-slope form

y-y1 = m(x-x1)

y-13 = 2 (x-4)

y = 2x - 8 + 13 =2x+5

Check:

when x = -2, y = 2(-2)+5 = 1 checks.
