Question

please solve all the parts

Answer 1

ABC is a right angled triangle
By using Pythagoras theorem
(hypotenuse)2=(base)2+(Prep)2
(AC)2=(24)2+(7)2
(AC)2=576+49
(AC)2=625 (625 is the square root of 25)
(AC)2=(25)2
powers of square are cut because both are in square root
AC=25.
Area of Triangle=1/2× base ×altitude
=1/2×24×7
=168/2
=84cm....
