Question

A rectangle is nine inches long and four inches wide. What is the area of the figure?

Answer 1

Hint: Here in this question, we are given the breadth and length of a rectangle and required to find the area of the given figure. So, we express area in terms of length and breadth of the rectangle and substitute the values of the known quantities. We have the formula for the area of the rectangle as: $A = l \times b$, where l and b are the length and breadth of the rectangle.

Complete step by step answer:
A rectangle is a two-dimensional shape with all four angles equal to ${90^ \circ }$ and opposite sides as equal. To determine the area of a rectangle, we have the standard formula $A = L \times B$ where L and B denote the length and breadth of the rectangle.

The unit for the area is square units. So, we are given the length of the rectangle as nine inches and the breadth of the rectangle as four inches. Now, since the dimensions of the rectangle are given to us in the unit inches. Then, the area of the square will be provided in the unit square inches. So, we have the area of the rectangle as $A = L \times B$.

Now, we substitute the value of breadth and length in the formula for the area of a rectangle. Hence, we get,
$ \Rightarrow A = \left( {9 \times 4} \right)$ square inches

Simplifying the calculations and finding the final answer for the area of the rectangle, we get,
$ \therefore A = 36$ square inches

Hence, the area of the rectangle is $36$ square inches.

Note: A rectangle is a two dimensional shape with all four angles equal to ninety degrees and opposite sides as equal. Generally the area is the region occupied by the thing.The area of a rectangle is defined as the region occupied by the quadrilateral region. Formula for perimeter of the rectangle is $2\left( {l + b} \right)$ and area of rectangle is $A = l \times b$ where l corresponds to length of rectangle and b corresponds to breadth of the rectangle.
