The length and breadth of a rectangle are 40 cm and 10 cm respectively. Its perimeter is:
(a) 100 cm
(b) 120 cm
(c) 140 cm
(d) none of these
Answers
ur answer is a) 100
Perimeter of rectangle is the sum of all its sides. Therefore, Length + breadth + length + breadth = Perimeter. 40+10+40+10 = 100 cm. The perimeter is 100cm.
Answer:
(a) The perimeter of the rectangle has a length of 40 cm and a breadth of 10 is 100 cm.
Step-by-step explanation:
Perimeter refers to the total distance around the boundary of a two-dimensional shape or figure. It is the sum of all the sides of the shape.
Perimeter is often used in geometry to determine the length of materials needed to surround or enclose an object.
Given,
Length of a rectangle, L = 40 cm
The breadth of a rectangle, B = 10 cm
The perimeter of rectangle, P = 2(L + B)
⇒ P = 2(40 + 10)
⇒ P = 2(50)
⇒ P = 100 cm
Hence, the perimeter of the rectangle has a length of 40 cm and a breadth of 10 is 100 cm.
