Test: Area & Perimeter - 1 - Class 5 MCQ

• The area of rectangle is given by length × breadth.
• So the area is 2m × 5m
• = 10m².

• Perimeter of a triangle =1^stside+2^ndside+3^rd side
• So, 20=5+4+3^rdside
• 3^rdside=20−9
• =11m. 

• Calculate no. of shaded boxes.
• It comes out to be 21.
• And each box has area of 1m².
• So the area of shaded region = 21m².

• Length of rectangle = x cm
• Breadth of rectangle = (x - 8) cm
• Perimeter of rectangle = 2(x + x - 8)
• = 2(2x - 8)
• Given 2(2x - 8) = 64
• ⇒  2x = 40  
• ⇒  x = 20
• L = 20, B = 20 - 8 = 12 

Area of rectangle = length x breadth 

area = 20 cm x 15 cm 

area = 300 cm²

• There are 2×5=10 squares and each square has an area of 4m²
• So, the area of rectangle =2×5×4
• =40m².

- The amount of surface in a closed plane figure is called the Area.
- Area measures the space inside a two-dimensional shape, such as a square, rectangle, or circle.
- Perimeter, option B, refers to the total length around a shape.
- Volume, option C, measures the space inside a three-dimensional object, which is irrelevant for plane figures.
- Therefore, the correct answer is A: Area, as it pertains to the extent of a surface within a closed boundary.

• Given, area = length × breadth
• ⇒ breadth = area÷length
• So, the breadth = 32/8
• = 4m.

Perimeter = 4× side length

160 = 4 × side length

side length = 160​ divided by 4

side length = 40cm
