Answer 2

Answer: a. The figure shown in the question is a rectangle.

The formula for area of A$= L X B$

Where length (L) is the longer side and Breadth (B) is the shorter side.

b. Given: The area of the figure is $= 63$

Length (L) of rectangle $= 2x-3$

Breadth of rectangle $=7$

Area of rectangle $= L X B$

To Find the value of $x$, Put the values in the formula.

$(2x-3) X 7 = 63$

$2x-3=\frac{63}{7}$

$2x-3= 9$

$2x=9+3$

$x= \frac{12}{2}$

$x=6$

So the value of $x$ is $6$.
