What’s the area and perimeter

Step-by-step explanation:

1. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:

x² = 19² - 17² = 72

x = √72

x = 8.5 (nearest tenth)

✔️Area = ½*b*h

b = 17

h = 8.5

Area = ½*17*8.5 = 72.25 units²

✔️Perimeter = 19 + 17 + 8.5 = 44.5 units

2. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:

x² = 5² + 13² = 194

x = √194

x = 13.9 (nearest tenth)

✔️Area = ½*b*h

b = 13

h = 5

Area = ½*13*5 = 32.5 units²

✔️Perimeter = 13 + 5 + 13.9 = 31.9 unit

3. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:

x² = 20² - 10² = 300

x = √300

x = 17.3 (nearest tenth)

✔️Area = ½*b*h

b = 17.3

h = 10

Area = ½*17.3*10 = 86.5 units²

✔️Perimeter = 17.3 + 10 + 20 = 47.3 unit

4. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:

x² = 5² + 14² = 221

x = √221

x = 14.9 (nearest tenth)

✔️Area = ½*b*h

b = 14

h = 5

Area = ½*14*5 = 35 units²

✔️Perimeter = 14.9 + 14 + 5 = 33.9 unit
