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