Question

A rectangle has length 40 cm and breadth 20 cm. How many squares with side 10 cm can be formed from it

Answer 1

Area of rectangle = (length × breadth) units²

Length = 40 cm

Breadth = 20 cm

∴ Area = (40 × 20) cm² 

= 800 cm²

Area of rectangle = 800 cm²

Area of square = (side × side) units²

side = 10 cm

∴ Area of square = (10 × 10) cm² 

= 100 cm² 

Required number of squares = `"Area of Rectangle"/"Area of 1 square"`

= `(800  "cm"^2)/(100  "cm"^2)`

= 8

8 squares can be formed.
