Question

( brainlies ) Can somebody help me with this?

Answer 1

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

Answer 2

Answer:

1. P = 122 | A = 930
2. P = 116 | A = 616
3. P = 128 | A = 1008

Solve(perimeter) ➕

1. 2 · (30 + 31) = 122
2. 2 · (14 + 44) = 116
3. 2 · (28 + 36) = 128

$\sf Formula$

P = 2 × ($l$ + $w$)

Solve(area) ❎

1. 31 · 30 = 930
2. 44 · 14 = 616
3. 36 · 28 = 1008

$\sf Formula$

A = $w$ × $l$
