Answer:
The answer is A
Step-by-step explanation:
2 less than three-fifths a number means that there is a number multiplied by 3/5 and you subtract two from it. 3/5n-2.
Less than or equal to is the one where the mouth is facing the right and there is a line under it
And then you have 41.
Answer:
99.9
Step-by-step explanation:
The area of a right angled triangle with sides of length 9cm, 12cm and 15cm in square centimeters is 54 sq cm.
The formula to calculate the area of a right triangle is given by:
Area of Right Triangle, A = (½) × b × h square units
Where, “b” is the base (adjacent side) and “h” is the height (perpendicular side). Hence, the area of the right triangle is the product of base and height and then divide the product by 2.
We know that the hypotenuse is the longest side. So, the area of a right angled triangle will be half of the product of the remaining two sides.
Given sides of the triangle:
a=9cm
b=12cm
c=15cm
From this we know that the hypotenuse is c. Are of the triangle will be obtained by the other two sides.
∴Area =
x 9 x 12
= 54
