Question

A basketball court is 20 meters long and 10 meters wide. What is the total sum of its sides?

A) 30 meters
B) 50 meters
C) 60 meters
D) 200 meters

Answer 1

Hint: We know that the rectangle has a property that the opposite sides of the rectangle are equal and all angles are 90 degrees. And also we can say that all sides of a rectangle are perpendicular to each other.

Complete step by step solution: Here given that :
DC = 20 meters
BC = 10 meters
And we know that by the property of rectangle –
DC = AB and BC = AD
Therefore, AB = 20 meters and AD = 10 meters
Now, total sum of its side= AB+BC+CD+DA
= ( 20+10+20+10 ) meters
= 60 meters

Hence, option (C) is correct.

Note: Sum of sides of rectangle is known as perimeter and to find the perimeter of rectangle there is a formula :
Perimeter of rectangle =$2 \times (length + breadth)$
Length is the longest side of the rectangle and Breadth is the smallest side of the rectangle.
( Here in this question
Length = AB = CD = 20 meters
And
Breadth = BC = AD = 10 meters
Therefore,
Perimeter of rectangle ABCD = $2 \times ( 20+10 ) $meters
= $2 \times 30 $ meters
60 meters.)
