If the length and breadth of a rectangle are 10cm and 20cm respectively,find the length of its diagonal
2 answers:
Answer:22.4 cm
Step-by-step explanation:
First draw the rectangle and divide it into two triangles.
Take one triangle out and with the length and breath solve for the hypotenuse using Pythagoras theorem
.: H^2 = 10^2 + 20^2
H^2 = 500
Find the square root of both sides of the equation
H = 22.4 cm = the length of the diagonal
L = 10
B = 20
so to find the diagonal you have to use Pythagorean theorem that is a^2 + b^2 = c^2
10^2 + 20^2 = X^2
X = root of 10^2 + 20^2
X = root of 100 + 400
X = root of 500
X = appox 22.36
