What is the percentage increase in the area of a rectangle if its length is increased by 20 \%?
Increase in the area of the rectangle is 44\%. After 20\% increase in Length and Breadth, (120/100*L)*(120/100*B) = 144/100*LB . Hence, increase in area = 144/100*LB – LB = 44/100*LB = 44\% Ans.
Is length and breadth of rectangle same?
A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).
What happens to area when diameter is halved?
If you think about it, radius is already half of the diameter so your area is already divided by 2, so if you cut the radius is half again, your area will be divided by 4.
What happens to the pressure if the area is halved and doubled?
When area is doubled , the impact on pressure acting on a object will be decreased . If area is halved, then the impact of pressure acting on the object will be increased.
What is the ratio of length and breadth of a rectangle?
The ratio of the length and breadth of a rectangle is 5:2 respectively. The respective ratio of its perimeter and area is 1:3 (irrespective of the unit).
What is the ratio between the length and breadth of a rectangle?
The length of a rectangle is halved, while its breadth is tripled. What is the percentage change in area? E. None of these The ratio between the length and the breadth of a rectangular park is 3 : 2.
What is the net increase in area on halving the rectangle?
The other rectangle is 5 cm x 15 cm. Its area becomes 75 sq cm. So the net increase in area on halving the length and tripling the breadth of the original rectangle is 50\%. Moreover the shape will change, that is the orientation of the figure gets rotated by 90 degrees.
What is the ratio between length and breadth of rectangular park?
The ratio between the length and the breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is: E. None of these An error 2\% in excess is made while measuring the side of a square.
