Question

1. Find the perimeter of the square whose area is
$2500m {?}^{2}$
2. What is the area of a handkerchief 40 cm square?

3. Find the area, in hectare, of a field whose length is 240m and breath 110 m.

4.a plot of land measures 500 m by 300 m. Find its area in hectare ​

Answer 1

1.Area of sqaure =2500m.

Length of one side = √2500 = 50.

Perimeter of square = 50×4 = 200.

2. Side of sqaure = 40m

Area of it = side×side

= 40×40

= 1600msquare

3. Area of field = L× B

= 240×110

=26400.

In hectare = 26400/10000

= 0.26400

4. Area of plot = 500×300

= 150000

In hectare = 150000/10000

= 15.0000
