Question

An isosceles triangle whose base is 16cm and one of its equal sides it 10cm find area

Answer 1

Answer:

48 cm²

Step-by-step explanation:

An isosceles triangle whose base is 16 cm and one of its equal sides it 10 cm

then, its altitude at base, will divide the base into two equal parts...

so... acc. to question:  by using pythagorus theorem, we will get the height of triangle(altitude):-

let altitude be x

10²=8²+x²

x= 6 cm

area of triangle= 1/2×base×height

                         =1/2× 16 cm×6 cm

                         = 48 cm²
