the areas of a square and rectangle are equal if the side of the square is 20 cm and the breadth of the rectangle 12 find the length of the rectangle and perimeter
Answers
Answer:
33.3 cm is length
Step-by-step explanation:
length is 33.3
lb is equal to a^2
12 * L is equal to 20*20
thus L = 100/3
L= 33.3 cm
Answer:
L= 100\3 = 33.3 cm
perimeter is 90.6 cm
Step-by-step explanation:
the area of square is equals to the area of the rectangle
area of square = a square
= 20× 20
= 400 cm square
therefore ,
area of rectangles = 400 cm square
area of rectangle = l×b
l× b = 400
l× 12= 400
l= 400÷ 12
l= 100÷3
perimeter of a rectangle = 2(l+ b)
= 2 ( 100/3 + 12/1)
= 2(100+36/3)
= 2×136/3
= 272/3
= 90.6cm
