This rectangular design is made from 6 squares. There are 2 small squares surrounded by 4 larger squares. The area of each small square is 1 cm^2.
What is the total area of the design?
Answers
Answer:
104 cm²
Step-by-step explanation:
Given area of small squares is 1 sq cm
so side AB = BC =CD = 1 cm
AC = AB + BC = 2cm
FD = FE + ED = 2 cm
GH = FD = 2 cm
But Given that FDHG is a square,
Since all sides are equal in a square
DH = FD = 2 cm
CH = CD + DH
= 1 + 2
Thus, CH = 3 cm
But AG = CH = PK = 3 cm
Given KAPG is a square, so
KP = KA = AG = PG = 3 cm
So, KC = KA + AC
= 3 + 2
= 5 cm
But given that SKCJ is square,
so SK = KC = CJ = JS = 5 cm
JH = JC + CH
= 5 + 3
= 8 cm
Now, given that JHQR is a square
so JH = HQ = QR = RJ = 8 cm
Now, if we look at the rectangle PQRS
length of rectangle SR
= SJ + JR
= 5 + 8
= 13 cm
breadth of the rectangle SP
= SK + KP
= 5 + 3
= 8 cm
Area of rectangle PQRS
= PS * RS
= 13 * 8
= 104 cm²
Hope, it helps !
