Question

The figure is formed by rectangles. Find the total area. The diagram is not to scale.

Answer 1

Answer:

correct option is d) 68 ft²

Step-by-step explanation:

The area of square is calculated by formula A = a²,

Where 'a' is side of square

In provided figure, we can see right side of rectangle in which two sides are given , which shows this is rectangle

and rest length is 10-2=8ft of left side rectangle

with refrence of figure-2

now calculate the area of first rectangle $A_{1}$ = (a1)² =8² =64 ft²

and the area of second rectangle $A_{2}$ = (a2)² =2² =4 ft²

Total area of diagram is;

A = $A_{1}\,+\,A_{2}$

A = 64 ft² +4 ft²

A = 68 ft²

Hence, correct option is d) 68 ft²

Answer 2

It's
$a1 = 2ft \times 2ft = 4ft {}^{2} \\ +a2 = 8ft \times 8ft = 64ft {}^{2} + 4ft {}^{2} \\ = 68ft {}^{2}$
so, it's d), 68ft^2
