The side of the square is - 40cm. Find the area of the square in (i) cm and (iii) m. Also If a man runs 3 round around the border of square then how much distance he will cover?
Answers
Correct question:
The side of the square is - 40cm. Find the area of the square in (i) cm² and (iii) m². Also If a man runs 3 rounds around the border of square then how much distance he will cover?
.
Given:
The side of a square = 40 cm
To be found:
- area of the square in (i) cm and (iii) m
- Also If a man runs 3 s around the border of the square then how much distance he will cover?
Now,
The formula for finding the area of the square = (Side)² unit sq.
So,
Area of the square = (40)² cm sq.
= (1600) cm sq.
Now,
Area of the square in m = 1600 ÷ 10000 = 0.16 m sq.
---
A man runs around the square
The Perimeter of the square = 4 × side unit
= 4 × 40
= 160 cm
Now,
If the man runs 3 times around the border of the square then the distance he will cover
= 3 × perimeter of the square
= 3 × 160
= 480cm
Hence,
- Area of square incm sq. = 1600cm sq. and in m sq. = 0.16 m sq.
- The man will cover 480 cm in total.
Well there is small mistake in the question.
The Question should be-
The side of the square is - 40cm. Find the area of the square in (i) cm sq and (iii) m sq. Also If a man runs 3 round around the border of square then how much distance he will cover?
___________
Answer
____________
The side of the square = 40cm (given)
Area of the square in cm²
= side²
= (40)²
= 1600cm²
Converting into m²
The area = 1600 = 0.16 m²
Now
Perimeter of the square
= 4×side
= 4 × 40
= 160cm
According to the question,
A man runs 3 rounds,
distance he will cover
= 3 × 160
= 480 cm
