powhuse is 26 cm, find the other two sidesThe sides of a tria3 at 25 p

1.	powhuse is 26 cm, find the other two sidesThe sides of a tria3 at 25 paisa per sq. m.m, 160 m and 200 m. Find the cost of ploughingrimeter of one square is 748.
Answer» Use Heron's formula with sides a,b and c s=a+b+c/2 Area=√s(s−a)(s−b)(s−c) Then, s = (120 + 160 + 200)/2 = 480/2 = 240 Area of triangle = √240(240−120)(240-160)(240−200)= √2401208040= 128100= 9600 sq m Therefore, Cost of ploughing a field = 9600 .25= Rs 2400

powhuse is 26 cm, find the other two sidesThe sides of a tria3 at 25 paisa per sq. m.m, 160 m and 200 m. Find the cost of ploughingrimeter of one square is 748.

Answer»

Use Heron's formula with

sides a,b and c

s=a+b+c/2

Area=√s(s−a)(s−b)(s−c)

Then, s = (120 + 160 + 200)/2 = 480/2 = 240

Area of triangle = √240(240−120)(240-160)(240−200)= √240*120*80*40= 12*8*100= 9600 sq m

Therefore, Cost of ploughing a field = 9600 *.25= Rs 2400
