Step by Step Solution

TABLE OF CONTENTS

Step-1 – Apply the concept of Rectangle

Rectangle is a quadrilateral. Opposite sides are equal and parallel. Measurement of all four angles is $90^{0}$ .

Step-2 – How to find the area of the Rectangle?

Area of rectangle is $length \cdot height$ square unit.

Step-3 – Distributive Property of Multiplication

Suppose a, b, and c is three real numbers.

Distributive Property of Multiplication

Property: $a (b + c) = a \cdot b + a \cdot c$

Example: $12 (3 + 4) = 12 \cdot 3 + 12 \cdot 4 = 36 + 48 = 84$

Step 4: Find the area of the Rectangle.

In this figure the length is (3x – 2) and height = 4

We know that area of Rectangle = $length \cdot height$

Find the area, using the distributive method of multiplication.

Property: $a (b + c) = a \cdot b + a \cdot c$

Area = $length \cdot height = (3 x - 2) \cdot 4 = 3 x \cdot 4 - 2 \cdot 4 = 12 x - 8$ square units

Area of the Rectangle is 12x – 8 sq unit.
