If the area of the red and blue square are 576 cm2 and 256 cm2 respectively, what is the area of the
right angle triangle (in cm2) formed?
Answers
Answer:
side of red square=24cm
side of square = 16cm
and third side of triangle =1/2×16×17.89
=8×17.89=143.1cm^2
Given,
The area of the red square = 576 cm2
The area of the blue square = 256 cm2
To find,
The area of the right-angled triangle (in cm2) formed.
Solution,
We can simply solve this mathematical problem using the following process:
As per mensuration;
The area of a square
= (length of each side)^2
Area of a right-angled triangle
= 1/2 × (base) × (height)
Now, according to the question;
The area of the red square
= 576 cm2 = (24 cm)^2
=> length of each side of the red square = 24 cm
And, the area of the blue square
= 256 cm2 = (16 cm)^2
=> length of each side of the blue square = 16 cm
Now, according to the figure;
The hypotenuse of the right-angled triangle formed
= length of each side of the red square
= 24 cm
The height of the right-angled triangle formed
= length of each side of the blue square
= 16 cm
Let us assume that the length of the base of the right-angled triangle formed is x cm.
Now, on applying Pythagoras theorem in the right-angled triangle formed, we get;
(base)^2 + (height)^2 = (hypotenuse)^2
=> x^2 + (16 cm)^2 = (24 cm)^2
=> x^2 = 576 cm2 - 256 cm2 = 320 cm2
=> x = 8√5 cm
=> length of the base = 8√5 cm
Now, the area of the right-angled triangle formed
= 1/2 × (base) × (height)
= 1/2 × (8√5 cm) × (16 cm)
= 64√5 cm2
= 143.1 cm2
Hence, the area of the right-angled triangle formed is equal to 64√5 cm2, that is, 143.1 cm2.
