Question

find area of iscosceles triangle whose perimeter is 64 and its perpendicular is 8 cm​

Answer 1

Step-by-step explanation:

it's perpendicular= 8 cm

and ATQ,

it is an isosceles triangle so it's other side will also be = 8 cm

perimeter given = 64 cm

also, perimeter = sum of all three sides

64 = 8+8+base

base = 64-16

base = 48 cm

find the area by heron's formula or draw an altitude of the triangle and find the height. then area = 1/2 × base × height
