Question

(i) Which measuring tool can be used to measure length in both feet and inches?
(ii) Choose the incorrect statement for the given image.

• A. (i) Measuring tape (ii) The red block is 2 feet or 36 inches longer than the blue block.
• B. (i) Measuring tape (ii) The combined length of both blocks is 12 feet.
• C. (i) Inch scale (ii) The red block is 7 feet long.
• D. (i) Inch scale (ii) The blue block is 5 feet or 60 inches long.

Answer 1

The correct option is A (i) Measuring tape (ii) The red block is 2 feet or 36 inches longer than the blue block.

$\text{Say:}$
$\bullet$ We know that we can measure the length in both inches and feet using a measuring tape.

$\bullet$ Now, let us observe the given image to find the incorrect statement.

$\text{Steps:}$
$\bullet$ The blue block starts from 0 mark and ends at 5.

$\bullet$ So, the length is 5 feet or 60 inches.

$\bullet$ The red block starts from 1 and ends at 8.

$\bullet$ So, the length of the red block is 8 – 1 = 7 feet or 84 inches

$\bullet$ Now, the difference in their lengths = 7 – 5 = 2 feet = 24 inches

$\bullet$ Combined length of both the block = 7 + 5 = 12 feet

$\bullet$ Hence, the red block is 2 feet or 24 inches longer than the blue block, and option B is the correct answer.
