What’s the answer help

Part one :-

In this part we will find area of small rectangle that is white in colour.

Given :-

Length = 4 (unit)Breadth = 5 (unit)

To find :-

Area

We know :-

Area of rectangle 1= Length × BreadthArea of rectangle 1= 4 × 5Area of rectangle 1 = 20 (unit)²

Part two :-

In this part we will find are of big rectangle

Given :-

Breadth = 4 + 2Breadth = 6 (unit)Length = 7 + 5Length = 12 (unit)

To find :-

Area

We know :-

Area of rectangle 2 = Length × BreadthArea of rectangle 2 = 6 × 12Area of rectangle 2 = 72

Part 3:-

Total Area = Area of rectangle 2 - Area of rectangle 1Total Area= 72 - 20Total Area = 52 (unit)²

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
