Question:

Consider the rectangle shown here.

A. State its area in square inches.

B. State its area in square feet, to the nearest tenth.

C. In general, A square inches equals how many square feet?

Answer 1

A. Area in square inches = 1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch =
`(1)/(144)` feet

Explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches = 1760 square inches

B. 1 foot = 12 inches

1 inch =
`(1)/(12)` feet

1 square inch =
`(1)/(144)` feet

∴ 1760 square inches =
`(1760)/(144)` feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch =
`(1)/(144)` feet
