5 pieces from the cardboard by cutting and pasting. Find the area of 3 such pieces.​

Answer 1

Answer:

♦ 15/14

Step-by-step explanation:

Given:

• A boy has a cardboard of length 10/7m and breath 5/4 m.
• He want to make 5 pieces from the cardboard by cutting and pasting.

To find:

• The area of 3 such pieces.

Solution:

• Area = l × b

Here,

• l is the length of a cardboard.
• b is the breadth of a cardboard.

• Area = 10/7 × 5/4
• Area = 50/28
• Area = 25/14

Now, we know that he want to make 5 pieces from the cardboard i.e, it has to be divided into 5 such pieces and then we will get area of one such piece.

• Area of one such piece = 25/14/5
• Area of one such piece = 25/14 × 1/5
• Area of one such piece = 5/14

Now,

• Area of 3 such pieces = 3 × 5/14
• Area of 3 such pieces = 15/14

∴ The area area of 3 such pieces = 15/14
