Question

(30 POINTS)

Answer 1

Using Pythagorean’s theorem
Side = 24 cm

Hence perimeter = 24+24+10+10
= 68 cm

Hence answer is 68cm

Answer 2

Answer:

${c}^{2} = {a}^{2} + {b}^{2}$

${b}^{2} = {c}^{2} - {a}^{2}$

${b}^{2} = {26}^{2} - {10}^{2}$

${b}^{2} = 676 - 100$

${b}^{2} = 576$

$\sqrt{ {b}^{2} } = \sqrt{576}$

$b = 24$

p = 10+10 +24+24

p= 68
