Question

Find the perimeter and area of the figure.

5 m
12 m
The perimeter is
meters.
The area is
square meters.

Answer 1

p=30

a=30

Explanation:

use pythagorean theorem to find the third side (you can use this bc its a right triangle)

5^2 + 12^2 = c^2

25+144=c^2

169=c^2

13=c

perimeter = 5 + 12 + 13 = 30

using heron's formula where s equals half the perimeter =15

square root[s(s-a)(s-b)(s-c)]

square root[15(15-5)(15-12)(15-13)]

square root[15(10)(3)(2)]

square root[900]

30
