Question

5. A metal plate measuring 32 cm by 12 cm is cut up into small squares of side length 4 cm. How many
squares will be cut?​

Answer 1

Answer:

24

Step-by-step explanation:

Area of metal plate = 32 cm × 12 cm

A = 384 cm²

Area of 1 small sqaure = 4 cm × 4 cm

A = 16 cm²

384 cm² ÷ 16 cm² = 24

24 sqaures can be cut

Answer 2

Step-by-step explanation:

let no pieces be x

area of rectangle = length ×breadth

length = 32cm breadth =12cm

area of rectangle = 32cm×12cm= 384cm^2

area of rectangle = x × area of square

area of square= a^2

side of square is 4cm

384cm^2 = x × 4cm × 4cm

x = 384 / 4× 4 = 24
