Need Help With This

Harrizon [31]

Answer:

Area: 28 square ft

Perimeter: 22 ft

Step-by-step explanation:

To find the area:

A=Lw

A is area, L is length, w is width

A=4*7

A=28

The area is 28 <em>square</em> feet

To find the perimeter:

P=2L+2w

P=2(7)+2(4)

P=14+8

P=22

The perimeter is 22 feet.

A right triangle has one angle that measures 69º. What is the measure of the other acute<br> angle?

gavmur [86]

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

The perimeter of a quadrilateral (four-sided polygon) is 41 inches. The longest side is twice as long as the shortest side. The

zhenek [66]

Answer:

The length of all four sides of a quadrilateral are 7 inches, 14 inches, 10 inches, 10 inches

Step-by-step explanation:

Let the shortest side be $x$

As per given information longest side = $2x$

and other 2 sides are equal in length but 3 more times that shortest side = $3+x$

Perimeter of Quadrilateral = 41 inches given

But perimeter of quadrilateral = sum of all sides

$x+2x+x+3+x+3=41\\5x+6 =41\\5x= 41-6\\5x=35\\x = \frac{35}{5}=7$

Shortest side = $7\ in$

Longest side = $2x= 2\times 7= 14 \ in$

Other 2 sides = $3+x=3+7 = 10 \ in$
