Question

The perimeter of a traingular park is 180 m and its sides are in the ratio 5:6:7. Find the area of the park.

Answer 1

Answer:

let sides be x

5x+6x+7x=180

18x=180

x=10

sides are 50, 60 and 70m

using herons formula

(50+60+70)/2

90 is semi perimeter

√ (90*(90-50)(90-60)(90-70))

√ (90*40*30*20)

√ (3600*600)

√(60*60*10*10*6)

600√6 m² is the area
