Question

The area of isosceles triangle is 48 cm2 if the altitude corresponding to the base of the triangle is 6cm find the perimeter of the triangle

Answer 1

Answer:

perimeter = 38 cm

Step-by-step explanation:

given, area= 48 cm^2

        altitude = 6cm

area of Δ = 1/2×base×height

48 = 1/2 × base × 6

base × 3 = 48

base = 48/3

base = 16

now it is an isoscles triangle

so base = 3rd side = 16

perimeter = 6 + 16 + 16

perimeter = 38
