The perimeters of two squares are 48 cm and 32 cm.
The perimeters of two squares are 48 cm and 32 cm. Find the perimeter of a third square whose area is equal to the difference of the areas of the two squares?
Answer/Solution
35.6 cm
Steps/Work
We know perimeter of square = 4(side)
So Side of first square = 48/4 = 12 cm
Side of second square = 32/4 = 8 cm
Area of third Square = 12*12 - 8*8
= 80 cm
So side of third square = 8.9 [because area of square = side*side]
Perimeter = 4*Side = 4*8.9 = 35.6 cm
Answer:B
So Side of first square = 48/4 = 12 cm
Side of second square = 32/4 = 8 cm
Area of third Square = 12*12 - 8*8
= 80 cm
So side of third square = 8.9 [because area of square = side*side]
Perimeter = 4*Side = 4*8.9 = 35.6 cm
Answer:B
