Question

using heron's formula find the area of an isosceles triangle whose perimeter is 16 cm & third side is 10 cm

Answer 1

Answer:

the area of isosceles triangle is 4056

the

Step-by-step explanation:

the herons formula is

√s(s-a)(s-b)(s-c)

so,√16(16-a)(16-b)(16-10)

perimeter is sum of all the sides

2x+10=16

2x=6

X=3

there fore the sides are 3,3,10

now we can find the area using herons formula

√s(s-a)(s-b)(s-c)

√16(16-3)(16-3)(16-10)

√16(13)(13)(10)

4056
