answer: 441cm^2
Step-by-step explanation:
length of AB=7cm+14cm
=21cm
length of BC=7cm+14cm
=21cm
length of CD=7cm+14cm
=21cm
length of AD=7cm+14cm
=21cm
Therefore, shape formed by line segments ABCD is a square.
Therefore, area of ABCD=side×side
=(21cm)^2
=441cm^2
Answer:
56 cm2
Step-by-step explanation:
Side of square = R(14cm)+r(7cm)
= 21cm
Area of shaded region = ar of square - area of sectors
Now,
AREA OF SECTORS = 1÷2(π(14)²+ π(7)²)
= 1/2(22/7 * 245)
= 385cm²
Put this in above equation ,
AREA = 21² -385
= 441- 385
= 56 cm²
