8. A triangle has sides with lengths of 6, 8, and 10 units, and a square has a
perimeter of 28 units. What is the positive difference, in square units,
between the area of the triangle and the area of the square?
a. 1
b. 4
c. 25
d. 100
e. 148

Difference between the area of the triangle and square is 25

Step-by-step explanation:

Area of the triangle = where s =

⇒ s = (6 + 8 + 10)/2 = 24/2 = 12

=

                                    = = = 24 sq. units

Perimeter of the square = 4 × side = 28

⇒ Side of the square = 28/4 = 7 units

⇒ Area of the square = (side)² = 7² = 49 sq. units

Difference = 49 - 24 = 25

use formula for the circle a=3.14
