Question

the perimeter of triangle is 32.38 cm.if one side is 10 cm 5mm nd second side is 12cm7 mm find the third side?
​

Answer 1

Answer:

10.26cm

Step-by-step explanation:

third side = 32.38cm - (10cm5mm + 12cm 7mm)

= 32.38cm - (10.05cm + 12.07cm)

= 32.38cm - 22.12cm = 10.26cm

Answer 2

Step-by-step explanation:

perimeter = 32.38

perimeter means some of all sides ,so,

third side=perimeter -- (first side + second side )

x = 32.38 -- (10.50 + 12.70)

x = 32.38 -- 23.2

x = 9.18
