Answers
Answer:
the perimeter of rectangle=255
SOLUTION - Q.1
Length of the rectangle = 17cm.
Breadth of the rectangle = 15cm.
Perimeter of a rectangle = 2(l+b) , Where l is the length and b is the breadth of the rectangle.
Here,
l = 17cm.
b = 15cm.
⇒ Perimeter of the rectangle = 2(17+15)
⇒ Perimeter of the rectangle = 2 × 32
⇒ Perimeter of the rectangle = 64cm.
SOLUTION - Q2
Sides of the Square = 12cm.
Area of a square = a² , Where a is the side of the square.
Here,
a = 12cm.
⇒ Area of the square = (12)²
⇒ Area of the square = 144 cm².
SOLUTION - Q3
Length of the calendar = 45cm.
Breadth of the calendar = 26cm.
The calendar is in the shape of a rectangle .
Area of a rectangle = l × b , Where l is the length and b is the breadth of the rectangle.
⇒ Area of the calendar = 45 × 26
⇒ Area of the calendar = 1170 cm².
