Question

A boy has a cardboard of length 10 by 7 and that 5 by 4 you want to make 5 pieces from the cardboard by cutting and pasting find the area of three such pieces
​

Answer 1

Step-by-step explanation:

The area of the 3 pieces is 15/14

Given ;

Length= 10/7

Breadth = 5/4

The area of cardboard is

A = l×b

A = 10/7 × 5/4

A = 25/14 m^2

we want it divide into five pieces and then we want three of those pieces.

so , we want 3 /5 of total area

The area of 3 piece is

A = 25/14 × 3/5

A = 15/14

Therefore, The area of the 3 pieces is 15/ 14
