The area of rectangle is 1.5 times of the area of the square. Length of rectangle is 3 times its breadth. If side of square is 15m what is the perimeter of the rectangle?
Answers
Answer:
Area of rectangle=1.5×Area of square
Given,
length(l)=3×breadth(b)
l=3b
Side of square=15meters
Area of square=side×side
=15×15
=225meter square
Area of rectangle=1.5×Area of square
=1.5×225
=337.5
Area of rectangle=length × breadth
337.5=3b×b
337.5=3(b square)
337.5/3=b square
112.5=b square
b=√112.5
b=10.6☺
length=3×breadth
length=3×10.6
length=31.8☺
Perimeter of rectangle=2(length+breadth)
=2(31.8+10.6)
=2(42.4)
=84.8meter
Answer:
84.8
