Question

A cardboard measures 27cm by 32 cm. How many 3 cm squares can be cut off from
this card board?
(A) 88
(B) 92
(C) 94
(D) 96​

Answer 1

Answer:

96 squares can be cut

Step-by-step explanation:

Length of cardboard =27 cm

• Breadth=32 cm
• Area= l × b
• = 27 × 32

= 864 cm^2

Area of 1 square = side^2

= 3^2

= 9 cm^2

Number of squares = area of rect./area of square

= 864/9

= 96

Answer 2

Answer:

96 squares of 3 cm can be cut off from the cardboard.

Step-by-step explanation:

Given :

Cardboard measures = 27 cm by 32 cm

Squares measure = 3 cm

To find :

Number of 3 cm squares can be cut off from the card board.

Solution :

$\textsf{\underline{\underline{Area of the cardboard = }}}$

★ Area = Length × Breadth

⇒ 32 × 27

⇒ 864 cm²

Area of the rectangle = 864 cm².

$\rule{300}{1.5}$

$\textsf{\underline{\underline{Area of the square = }}}$

★ Area = Side × Side

⇒ 3 × 3

⇒ 9 cm².

Area of the squares = 9 cm².

$\rule{300}{1.5}$

$\textsf{\underline{\underline{Number of 3 cm squares = }}}$

Divide the area of the cardboard by the area of each square.

⇒ 864 ÷ 9

⇒ 96

$\therefore$ 96 squares of 3 cm can be cut off from the cardboard.
