Question

Find the area of a triangle whose sides are 13cm, 10cm and 15√2cm respectively.​

Answer 1

Answer: 60

Step-by-step explanation:

here,

let construct a perpendicular line

we have h=13,b=10/2=5,h=?

now, p=(√h²-b²)

p=(√13²-5²)

p=12

again,

formula of area of triangle is  (height ×base)÷2

we have height =12,base =10

area of triangle=  (height ×base)÷2

=(12×10)÷2

=120÷2

=60 # ans
