1.	Find the area of the triangle whose perimeter is 3ocm and its sides are in the ratio 1:3:2
Answer» ANSWER: Step-by-step explanation: PEREMETER = 30cm ratio of the SIDES = 1:2:3 ∴ each SIDE = 30/1+2+3=30/6=5 side 1 =5∧1=5 side 2=5∧2=10 side 3=5∧3=15 area of triangle = 1/2 ∧h∧b = 1/2∧5∧10=25cmsq

Find the area of the triangle whose perimeter is 3ocm and its sides are in the ratio 1:3:2

Answer»

Step-by-step explanation:

PEREMETER = 30cm

ratio of the SIDES = 1:2:3

∴ each SIDE = 30/1+2+3=30/6=5

side 1 =5∧1=5

side 2=5∧2=10

side 3=5∧3=15

area of triangle = 1/2 ∧h∧b

= 1/2∧5∧10=25cmsq
