Question

A carpenter had to make a triangle with sides 5, 6, 5 units. By mistake he made one with sides 5, 8, 5 units. The difference between their areas is _________. (a) 16 sq units (b) 2 sq units (c) 4 sq units (d) 0 sq units

Answer 1

Step-by-step explanation:

area of actual triangle that he had to make

s = (5+5+6)/2

s= 8

a = √(8 x 3 x 3 x 2)

a1= 12 sq units

 

area of triangle that the carpenter made

s = (5+5+8)/2

s = 9

a = √(9 x 4 x 4 x 1)

a2 = 12 sq units

so difference a1 - a2 = 12 - 12 =0 sq units
