Answer:

  1. <u>P = 122 | A = 930</u>
  2. <u>P = 116 | A = 616</u>
  3. <u>P = 128 | A = 1008</u>

<h3>Solve(perimeter) ➕</h3>
  1. 2 · (30 + 31) = 122
  2. 2 · (14 + 44) = 116
  3. 2 · (28 + 36) = 128

\sf Formula

<em>P</em> = 2 × (l + w)

<h3>Solve(area) ❎</h3>
  1. 31 · 30 = 930
  2. 44 · 14 = 616
  3. 36 · 28 = 1008

\sf Formula

A = w × l

Answer:
(a)

Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

PLS HELP ME ASAP FOR 1, 2, 3, and 4 (SHOW WORK!!) + LOTS OF POINTS!!
Lera25 [3.4K]
1/2in = 16 mi
2 3/4 in without whole numbers [(denominator ×whole) + numerator] / denominator
4×2 = 8 +3 = 11/4
Find common denominator for 1/2 and 11/4 (common D Is 4)
Multiply 1/2 by 2/2
2/4 in = 16 mi divide this by 2
2/4 ×1/2 = 1/4
16 /2 = 8
1/4 = 8
1/4 goes into 11/4 11 times
Multiply 8 times 11
88 miles (D)

End zone to end zone is = length so his scale is 6 in and in real life it is 360 ft
To find scale divide 360 by 6
1in = 60 ft (B)

160 ft wide
(divide 160 by 60 ft ) fraction
160/60 is a fraction now simplify
16/6
Common factors of both numbers is 2
Simplify by 2
8/3
Make into whole number fraction
3 goes into 8 two times (2×3=6)(2 becomes whole number) while there's is 2 left over( 8 -6=2) (becoming the numerator)
2 2/3 in (B)

120 ft long
80 ft wide

24 in is scale of "long"
Divide 120 by 24
120÷24=5
So 5in in scale equals 1ft in real life
To find width in scale divide 80 by 5
80/5= 16in (A)

If you have any trouble understanding feel free to let me know I will try to explain as best as I can :)

 m∠A = 42 and m∠C = 57. Find m∠B.<br>A. 81<br><br> B. 99<br><br> C. 132<br><br> D. 147
faltersainse [42]
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
