Answer 1

Answer:

B. 3 by 12

Step-by-step explanation:

The rectangle is four times as long as it is wide,

(3 times 4=12)

and has an area of 36

(3 times 12=36)

so this is the correct answer.

Answer 2

If the area of the given rectangle is 36 square inches, then the length of rectangle is 12 inches and the breadth of rectangle is 3 inches.

What is area?

"Area is the quantity that expresses the extent of a region on the plane or on a curved surface."

What is rectangle?

"A rectangle is a shape with four straight sides and four angles of 90 degrees (right angles)."

Area of rectangle = 36 square inches

Let the width of rectangle be y

Length of rectangle be 4y

Area of rectangle = length × breadth

y×4y = 36

$4y^{2} = 36$

$y^{2}=9\\y=\sqrt{9}$

$y=3$

Hence, the width of the rectangle is 3 inches and the length of the rectangle is 12 inches.
