Question

ABC is a triangle in which ab is equal to AC is equal to 4 and angle is equal to 90 degree calculate the area of triangle ABC

Answer 1

Area of a triangle =1/2× base ×height
A=1/2×AC×AB
A=1/2×4×4
A=8

Answer 2

ABC a triangle is equal to AC
AC is equal to 4
4 is equal to 90 degree
ATQ area of triangle is side+ height+base
90+4+b
94 value of b is
triangle is a linear pair
so 180-94=86
b= 86
area of triangle =94+86= 180
