Answer:
Step-by-step explanation:
a. 4/7 + 3/8 = 32/56 + 21/56 = 53/56
b. 2/5 + 5/8 = 16/40 + 25/40 = 41/40 = 1 1/40
c. 3/8 + 2/10 = 15/40 + 8/40 = 23/40
d. 4/5 + 2/6 = 24/30 + 10/30 = 34/30 = 1 4/30 = 1 2/15
e. 5/6 + 2/9 = 15/18 + 4/18 = 19/18= 1 1/18
f. 2/15 + 5/12 = 8/60 + 25/60 = 33/60 = 11/20
Difference between the area of the triangle and square is 25
Step-by-step explanation:
- Step 1: Find the area of the triangle given its 3 sides using the Heron's formula.
Area of the triangle = where s =
⇒ s = (6 + 8 + 10)/2 = 24/2 = 12
=
= = = 24 sq. units
- Step 2: Find the area of the square with perimeter = 28 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
- Step 3: Find the difference between the area of the square and triangle.
Difference = 49 - 24 = 25
