Question

A boy walks around a square field whose one side is 60m. If he walks two round the field, find the total distance he covered.
a) 120m
b) 240m
c) 480m​

Answer 1

Step-by-step explanation:

Find the area of the rectangle whose dimensions are:

(i) length = 24.5 m, breadth = 18 m

(ii) length = 12.5 m, breadth - 8 dm.

ANSWER:

(i) Length = 24.5 m

Breadth = 18 m

∴ Area of the rectangle = Length × Breadth

= 24.5 m × 18 m

= 441 m2

(ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m [since 1 dm = 10 cm and 1 m = 100 cm]

∴ Area of the rectangle = Length × Breadth

= 12.5 m × 0.8 m

= 10 m2

Answer 2

area of the square feild is 60m =boy take to walk around the feild 1time 60 m means 2 time 60x2=120m
