Find the perimeter of a rectangle whose length is 150m and the diagonal is 170m.
Answers
GIVEN
We are given a rectangle with length 150m and diagonal 170m
TO FIND
We need to find the perimeter of the rectangle
In order to find the breadth, we can use Pythagoras theorem because all angles of a rectangle are 90°.
PROCEDURE
To find the breadth, we apply Pythagoras theorem.
==> (length)^2 + (breadth)^2 = (diagonal)^2
==> 22500 + breadth^2 = 28900
==> breadth = 80m
Perimeter = 2 (length + breadth)
Perimeter = 460m
Answer:
Step-by-step explanation:
★ Concept :-
✪ Here the concept of Perimeter of Rectangle has been used. As we see, that we are given the length and the diagonal of rectangle. Then firstly, we will find out the breadth of the rectangle. After that, by applying the required values in the formula of Perimeter of Rectangle we will get the answer.
Let's do it !!!
